Embodiment 2 FIG. Next, a second embodiment will be described with reference to FIG. FIG. 2 is a schematic diagram showing a configuration of the small fuel cell system according to Embodiment 2. In FIG. 2, the same elements as those in the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

The small fuel cell system according to Embodiment 2 is an example in which the present invention is embodied as a city gas reforming type fuel cell system having a rated output of 5 kW class. A reforming type fuel adjustment and supply device 102 is used, and a phosphoric acid type fuel cell type fuel cell power generation device 202 is used as the fuel cell power generation device 2. In the following description, when simply referred to as the fuel adjustment and supply device 102, it means the city gas reforming type fuel adjustment and supply device 102.
When it is referred to as 02, it means the fuel cell power generation device 202 of the phosphoric acid type fuel cell type.

A major difference from the first embodiment is that the fuel is city gas instead of methanol, and the fuel cell is not a polymer electrolyte fuel cell power generator (PEFC) but a phosphoric acid fuel cell (PAFC) power generator. There is a point. Also, unlike methanol, city gas contains a sulfur compound such as mercaptan as an odorant, and requires a desulfurizer. Also, the reforming temperature is 250-300 of methanol.
The temperature is about 700 ° C. higher than the temperature, and the reforming catalyst is completely different. On the other hand, the operating temperature of phosphoric acid fuel cells is 200
C., which is higher than about 80 ° C. of the polymer electrolyte fuel cell, and the allowable CO concentration and the operating current density are different. Therefore, unless these pieces of information are shared, the fuel adjustment supply device and the fuel cell power generation device cannot be operated in cooperation with each other.

Therefore, the fuel adjusting and supplying device 102 includes a city gas intake pipe 25, a desulfurizer 26, a city gas reformer 33, a combustor 12 for giving necessary heat to the reformer 33, and a steam reformer. A water tank 20 for storing quality water, a steam generator 29, an air blower 15 for sending combustion air to the combustor, and a control device 5 for controlling the operation of these devices and a built-in power supply for the device A battery 9 and the like are mounted.

On the other hand, the fuel cell power generation device 202 includes a phosphoric acid type fuel cell stack 31, a heat exchanger 27 for cooling water, an air blower 16 for sending air to the fuel cell, and a device for adjusting a generated voltage. A converter 17, a radiator 18 for releasing heat generated in the fuel cell stack to the atmosphere, a cooling water circulation piping port 30 for hot water use, a power takeout cable 23, and a control device 6 for controlling the operation of these devices And a built-in battery 10 serving as a power source for the power supply.

A moving caster 24 is attached to the fuel adjusting / supplying device 102 and the fuel cell power generating device 202, and has a structure excellent in portability as in the first embodiment. . When the small fuel cell system is used as a household power supply, the casters 24 may be removed and used as a stationary type.

As in the first embodiment, between the fuel adjustment and supply device 102 and the fuel cell power generation device 202,
2, a pipe 4 for moving the fuel off-gas of the fuel cell power generation apparatus 202 to the fuel adjustment and supply apparatus 102, the fuel adjustment and supply apparatus 102, and the fuel cell power generation apparatus 202.
A signal transmission cable 7 for mutually transmitting information to and from the vehicle, a charging cable 8 for charging the built-in battery 9 of the fuel adjustment and supply device 101 with electric power generated by the fuel cell power generation device 201, and the like are detachable. It is provided in. Therefore, transportation, loading, unloading, and assembling of the fuel adjustment and supply device 102 and the fuel cell power generation device 202 are convenient, and the device can be excellent in earthquake resistance.

The city gas reformed gas reformed by the fuel adjusting and supplying device 102 is supplied from the fuel adjusting and supplying device 102 to the fuel cell power generation device 202 through the fuel gas transfer pipe 3, and is supplied to the phosphoric acid type fuel cell stack 31. Fuel gas (fuel off-gas) that has been used for power generation in
Through to the combustor 12 of the city gas reformer 33,
Used as heat required for the reforming reaction.

The transmission of information through the signal transmission cable 7 between the fuel adjustment supply device 102 and the fuel cell power generation device 202 is as important as in the first embodiment. Further, the fuel adjustment and supply device 102 requires the built-in battery 9 for driving the auxiliary devices such as the control device 5, the air blower 15, and the steam generator 29, and the fuel cell as in the first embodiment. It is necessary to charge from the power generation device 202. When a commercial power supply such as a household power supply can be used, a commercial power supply may be used instead of charging the built-in battery 10 of the fuel adjustment supply device 102 from the fuel cell power generation device 202.

The exhaust heat of the cooling water of the phosphoric acid type fuel cell can be used to make hot water. That is, instead of passing the heat generated in the fuel cell stack 31 to the radiator 18 for releasing it to the atmosphere and cooling it, the cooling water is circulated from the cooling water circulation piping port 30 using hot water to the hot water storage tank, so that the hot water is circulated. Can be stored and used.

The second embodiment is configured as described above, and can provide the same effects as in the first embodiment.

As a modification of the above-described second embodiment, a compressed natural gas type, an LPG gas type, or a liquefied butane gas type fuel adjustment supply device can be used as the fuel adjustment supply device 1. In this case, a reformer having a configuration similar to that of the city gas reformer 33 can be used. However, it is necessary to change the pressure of the compressed gas, evaporate the liquefied gas, and the like in accordance with each fuel. Therefore, it is difficult to use the same fuel adjustment supply device 102. Therefore, another type of fuel adjustment and supply device 1 is provided. In the case of a desulfurized gasoline type, not a steam reforming system but a partial oxidation system in which reforming is performed while burning a part of fuel is often used. Will be different. However, in any case, power generation can be performed in cooperation with the polymer electrolyte fuel cell type fuel cell power generation device 201 or the phosphoric acid type fuel cell type fuel cell power generation device 202. Further, other fuel cells, for example, a solid oxide fuel cell and the like can also be used.

Embodiment 3 Next, a third embodiment will be described with reference to FIG. FIG. 3 is a schematic diagram showing the configuration of the small fuel cell system according to Embodiment 3. In FIG. 3, the same elements as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified.

The small fuel cell system according to the third embodiment is an example in which the present invention is embodied as a hydrogen cylinder type fuel cell system having a rated output of 5 kW class. Fuel adjustment supply device 10
3, a fuel cell power generator 201 of a polymer electrolyte fuel cell type is used as the fuel cell power generator 2. In the following description, when simply referred to as the fuel adjustment and supply device 103, it means the hydrogen adjustment type fuel adjustment and supply device 103.

In the hydrogen cylinder type fuel cell system according to Embodiment 3, two hydrogen compression cylinders 32 are mounted on the hydrogen cylinder type fuel adjustment and supply device 103, similarly to the conventional one shown in FIG. Figure 8
Is a small fuel cell system corresponding to the conventional example. However, different from the conventional example, the fuel cell system includes the fuel adjustment supply device 103 and the fuel cell power generation device 2.
It is obvious at first glance that the device is excellent in portability as in the first embodiment.
Therefore, when it is used as a portable power source, it is often necessary in the event of an emergency such as an earthquake disaster, and it is necessary to quickly install the device through a narrow space and start power generation as soon as possible. As in Embodiment 3, the fuel cell system includes the fuel adjustment supply device 103 and the fuel cell power generation device 2.
In the case of being divided into two, it can be carried in through a narrow passage that is easy to carry, and can be suitable for a purpose such as a portable power supply.

In the small fuel cell system according to Embodiment 3, the compressed hydrogen gas in the hydrogen compression cylinder 32 is
After the pressure is reduced by the fuel adjustment and supply device 103, the fuel is supplied from the fuel adjustment and supply device 103 to the fuel cell power generator 201 through the fuel gas transfer pipe 3, and is used for power generation in the polymer electrolyte fuel cell stack 13. When pure hydrogen is used as the fuel, the fuel can be consumed at almost 100% utilization rate. Therefore, it is not necessary to move the fuel off-gas of the fuel cell power generation apparatus 201 to the fuel adjustment and supply apparatus 103. The pipe 4 in the first embodiment is not always necessary.
Therefore, this pipe 4 is not shown in FIG.

According to the third embodiment, since the configuration is as described above, the same effects as in the first embodiment can be obtained.

As a modification of the second embodiment, a hydrogen storage alloy may be used instead of pure hydrogen for the fuel. In this case, since the hydrogen storage alloy needs to be warmed, it is more efficient to circulate hot water from the fuel cell power generator 201 side. In this case, it is necessary to connect a cooling water circulation pipe separately. Further, when the hydrogen storage alloy is to be refilled with hydrogen, the cooling water circulation pipe can be connected to an external pipe to fill the hydrogen. When liquid hydrogen is used, it is necessary to provide the fuel adjustment and supply device 1 with a device that converts the evaporated hydrogen into water by catalytic combustion.

Embodiment 4 Next, a fourth embodiment will be described with reference to FIG. FIG. 4 is a schematic diagram showing the configuration of the small fuel cell system according to Embodiment 4.

The small fuel cell system according to the fourth embodiment is different from the first embodiment in that the number of the methanol reforming type fuel adjusting and supplying devices 101 is two, and the two methanol reforming type fuel adjusting and supplying devices 101 are provided. This is a small-sized fuel cell system with a rated output of 5 kW, in which one polymer electrolyte fuel cell power generator 201 is connected to 101 (indicated by reference numerals 101a and 101b in the drawings).

In FIG. 4, reference numeral 40 denotes a methanol reforming type fuel adjustment and supply device 101a and a fuel cell power generation device 20.
Reference numeral 41 denotes a pipe and a wire between the fuel reformer 101 and the fuel cell power generator 201.

According to the fourth embodiment, since the power is generated by using the two fuel adjusting and supplying devices as described above, the duration of the power generation becomes long. Further, the reforming amount of one methanol reforming type fuel adjustment and supply device can be kept constant, and the other methanol reforming type fuel adjustment and supply device can be changed in conjunction with the load. For example, even in the same methanol reformer, the methanol reforming type fuel adjustment and supply device 1 is set to a steam reforming system to perform constant reforming, and the methanol reforming type fuel adjustment and supply device 1 is changed to change the reforming amount. If the load is made to follow the load by adopting the partial oxidation method which is easy to cope with, it is possible to generate electric power which can sufficiently cope with a large load fluctuation. Further, power generation can be continued even if a failure occurs in one of the fuel adjustment and supply devices, so that reliability is improved.

Embodiment 5 Next, a fifth embodiment will be described with reference to FIG. FIG. 5 is a schematic diagram showing the configuration of the small fuel cell system according to Embodiment 5.
In FIG. 5, the same elements as those in the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

In the small fuel cell system according to the fifth embodiment, in the first embodiment, two solid polymer fuel cell power generators 201 are provided for one methanol reforming type fuel adjustment and supply device 101 in the first embodiment. (In the drawing, 201a, 2
A small fuel cell system having a rated output of 10 kW is connected to the fuel cell system.

In FIG. 5, reference numeral 42 denotes a pipe and wiring between the methanol reforming type fuel adjustment and supply device 101 and the polymer electrolyte fuel cell power generator 201a, and 43 denotes a methanol reforming type fuel adjustment and supply device 101a. It is a pipe and wiring between the solid polymer fuel cell power generator 201b.

According to the fifth embodiment, since the two fuel cell power generators are connected as described above, even if one of them is operated at 5 kW output, the two are operated in tandem, so that If it is, a maximum output of 10 kW can be output. In addition, a system in which one is operated constantly and the other is operated while following a load becomes possible. Further, even if one of the units fails, power generation can be continued.

Embodiment 6 FIG. Next, a sixth embodiment based on FIG. 6 will be described. FIG. 6 is a schematic diagram showing a configuration of a small fuel cell system according to Embodiment 6.
In FIG. 6, the same elements as those in the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

The small fuel cell system according to the sixth embodiment differs from the first embodiment in that the fuel reforming / supplying device 101 of the methanol reforming type and the power generating device 201 of the polymer electrolyte fuel cell are two each (in FIG.

Embodiment 8 FIG. Next, an eighth embodiment will be described with reference to FIG. FIG. 8 is a schematic diagram showing a configuration of a small fuel cell system according to Embodiment 8. In FIG. 8, the same elements as those in the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

The small fuel cell system according to Embodiment 8 is an example in which the fuel cell system of the present invention is embodied as a methanol reforming type fuel cell system with a rated output of 5 kW. Is different from the first embodiment in that the fuel adjustment supply device 101 and the fuel cell power generation device 201
, A power storage and transmission device 301 is further connected to the fuel cell power generation device 201.

The power storage and transmission device 301 includes a large capacity battery 61 and an electric controller 64 as a control device.
And a signal transmission cable 62 disposed between the fuel cell power generation device 201 and the power storage and power transmission device 301, a DC power transmission cable 63 from the fuel cell power generation device 201 to the power storage and power transmission device 301, and the like. Is provided.

In the first embodiment, the generated power is transmitted directly from the fuel cell power generator 201 to an external load. In the eighth embodiment, the power is transmitted from the fuel cell power generator 201 to the power storage and power transmission apparatus 301. After that, power is transmitted from the power storage and transmission device 301 to an external load.

The large-capacity battery 61 is mounted on the power storage and transmission device 301 as described above. If necessary, the electric power charged in the large-capacity battery 61 is transmitted to an external load in addition to the generated power. Accordingly, even when the external load changes greatly, it is possible to follow and transmit power. As a result, the need for the fuel cell power generator 201 to change the power generation amount in accordance with the change in the external load as in the first embodiment is reduced, and it is sufficient to continuously generate a substantially constant amount of power. Becomes Eighth Embodiment Having Such a Configuration
Is particularly effective in applications where the external load fluctuates greatly.

The large-capacity battery 61 is, for example, a vehicle such as the Toyota Prius vehicle name "Prius", which has recently been put into practical use as a so-called hybrid vehicle that runs using a gasoline engine and a battery drive motor. A nickel-metal hydride secondary battery manufactured by Matsushita Battery and the like, which is mounted on the vehicle, can be used. In addition, a lead storage battery which is generally widely used as a battery for an automobile, a large lithium secondary battery which is experimentally manufactured for an electric vehicle, and the like can also be used.

The power storage and transmission device 301 equipped with the large capacity battery 61 can be used alone as an emergency power source separately from the fuel cell power generator 201. The power storage and transmission device 301 includes the fuel adjustment and supply device 1.
As in the case of the fuel cell power generator 01 and the fuel cell power generation device 201, the transport casters 24 are provided, so that it is portable. Therefore, in the event of a disaster such as an earthquake, first, the power storage and transmission device 301, which has been charged in advance using a commercial power supply, is carried to the destination, and power transmission is started immediately. After that, the fuel adjustment supply device 101 and the fuel cell power generation device 201 are carried in and connected to the power storage and power transmission device 301, and power generation is started immediately to charge the large capacity battery 61. With such a usage, it is possible to continuously perform power transmission that can be performed only for a short time with the power storage and power transmission device 301 as long as the fuel continues.

The electric controller 64 as a control device of the power storage and transmission device 301 includes information on the remaining power amount of the large-capacity battery 61 incorporated in the power storage and power transmission device 301, the information on the transmitted power amount to the outside, and the fuel cell power generation device 201. The amount of power generated by the fuel cell power generator is set based on the amount of current that can be generated and transmitted from the device. Then, this is instructed to the fuel cell power generator 201.

On the other hand, the fuel cell power generator 201 is the fuel adjustment and supply device 10 transmitted from the fuel adjustment and supply device 101.
The fuel utilization rate is set based on the first type information, and information on the generated current value is transmitted to the fuel adjustment supply device 101 based on the power generation amount instructed from the power storage and transmission device 301. The amount of current that can be generated is calculated from the remaining amount of fuel transmitted from 101 and the value is transmitted to power storage and transmission device 301.

Further, the fuel adjustment and supply device 101 sets the amount of fuel release and the reforming amount based on the generated current information transmitted from the fuel cell power generation device 201, and adjusts and supplies the fuel to the fuel cell power generation device 201. The type information of the device 101 and the remaining amount of fuel are transmitted. Further, based on the charging capacity of the large-capacity battery 61 and the amount of transmission power, the power supply control unit 201 instructs the fuel cell power generation device 201 to transmit power with a constant current within a range that does not cause excessive charging. Then, the fuel cell power generation device 201 instructs the fuel adjustment supply device 101 on the reforming amount according to this command.

When power transmission from the fuel cell power generation device 201 becomes possible, DC power is transmitted from the fuel cell power generation device 201 to the power storage power transmission device 301 using the DC power transmission cable 63, and the large capacity battery 61 is charged.

The large-capacity battery 61 receives the charge from the fuel cell power generation device 201 while transmitting power following the external load, but is actually transmitted to the external load via the large-capacity battery 61 and The stored power is charged in the large-capacity battery 61.

It should be noted that the present fuel cell system can basically respond to an external load with either DC or AC. In the event of a disaster such as an earthquake, it is considered that power is often transmitted by alternating current. And even in the exchange, there is a distinction between 50HZ and 60HZ depending on the area, but this switching is easy for the parties. However, if the commercial power supply also survives and only the voltage drops, it is necessary to tune the frequency characteristics with an inverter. Even in such a case, it is possible to easily cope with the problem by applying an existing technology such as an inverter attached to a home solar cell panel.

According to the eighth embodiment, since the configuration is as described above, first, power transmission is started by the power storage and transmission device 301, and then the fuel adjustment and supply device 101 and the fuel cell power generation device 201 are connected. Thus, power transmission can be continued for a long time. Further, since the apparatus is divided into three parts, the apparatus has excellent portability. Therefore, there is an effect that quick power transmission and long-time power transmission can be performed while maintaining portability.
