Description
Technical Field
The invention relates to the technical field of fuel cells, in particular to a stack heat exchange structure for a high-temperature fuel cell and application thereof.
Background
Thermal management is the core technology of the fuel cell stack, and the design of thermal management dominates the design of the fuel cell stack. The main purpose of thermal management is to remove the heat generated by the membrane electrode from the stack by means of heat transfer to bring the stack to thermal equilibrium. The fuel cell stack mainly has two forms of internal cooling and external cooling, each of which is classified into two cooling methods, an air cooling method and an oil cooling method, according to a cooling medium. The internal air cooling method is that high-metering-ratio cathode air exchanges heat with a cathode structure, and the air is used as a cooling medium to carry the heat out of the electric pile. The oil cooling method is that heat conducting oil with high specific heat exchanges heat with a heat interface of a relatively independent channel. Systems with different power ranges require different types of thermal management methods, for example, the air cooling method is generally applied to a high-temperature methanol fuel cell stack with a power of less than 1kW, and due to the low heat capacity and heat conductivity of air, a large temperature gradient is formed in the effective area of the stack, which affects the temperature uniformity of the membrane electrode, and the air cooling method is generally applied to a stack with a small effective area. At the same time, the air cooling method requires an excessively high air flow rate, which greatly increases the power consumption of the auxiliary components of the system, thereby reducing the system efficiency. The oil cooling method is suitable for a high-temperature methanol fuel cell stack with the power of more than 1kW, and as the heat conduction oil has higher specific heat capacity and heat conductivity coefficient, only lower temperature gradient and parasitic power consumption of a pump are generated in the cooling process. The biggest technical challenge of the oil cooling method is the sealing problem of the heat transfer oil circulation circuit, and the existing oil cooling technology as shown in fig. 3 is very easy to cause the heat transfer oil to leak, thereby causing the irreversible damage to the electric pile caused by the membrane electrode pollution.
Based on the structure, the separation of the heat conduction oil circulation circuit and the membrane electrode is realized, the pollution of an oil way to the membrane electrode is effectively avoided, and the uniform cooling is the problem to be solved urgently by the high-temperature fuel cell stack.
