Embodiment
Fig. 2 is for showing the exploded view of the fuel cell with the utility model tip plate configurations.In Fig. 2, the utility model tip plate configurations 1 is to be applied to fuel cell, can be used to as the outermost end plate of fuel cell.Tip plate configurations 1 is to comprise end plate body 10 and conducting strip 20, and tip plate configurations 1 is single structure, below in literary composition those members will be described in detail in detail respectively.
Cell of fuel cell 2 is to comprise: first bipolar plates 30, first diffusion layer 40, mea 50, second diffusion layer 60 and second bipolar plates 70.Mea 50 is to be fixed between first diffusion layer 40 and second diffusion layer 60 by interlayer, and the outer surface of the outer surface of first diffusion layer 40 and second diffusion layer 60 is to attach first bipolar plates 30 and second bipolar plates 70 respectively.
First bipolar plates 30 is to be provided with more than one perforation 31.Mea plate 50 is to be provided with more than one perforation 51.Second plate plate 70 is to be provided with more than one perforation 71.Those perforation 31,51,71 are bored a hole 103 corresponding with those of end plate body 10 respectively.
Fig. 3 is for showing the stereogram of the fuel cell with the utility model tip plate configurations.Outermost two outer surfaces of cell of fuel cell 2 are to be inserted and put by two tip plate configurations 1 respectively.(for example: screw rod and nut) screw rod is worn the perforation 103 etc. of tip plate configurations 1 on perforation 71, the right side of perforation 51, second bipolar plates 70 of perforation 31, the mea 50 of the perforation 103 of passing through in the tip plate configurations 1 in left side, first bipolar plates 30 by the assembly 3 that is spirally connected, fix via the nut interlocking again, so just become a fuel cell.
Moreover, use the fuel cell of the utility model tip plate configurations, also can two or three or the cell of fuel cell 2 more than four (containing) be set, and become a fuel cell pack at interlayer between left-hand end plate structure 1 and the right-hand end plate structure 1.
The utility model end plate body can use corrosion resistance and insulating properties macromolecule resin, and mixes with glass fibre and strengthen the end plate main body structure, and its bulk strength can approach the degree of conventional al alloy end plate.On the other hand, the utility model end plate body is about 1.75 to 2.7 respectively with the proportion of conventional al alloy end plate, therefore, relatively going up of weight, the utility model end plate body is far beyond the more weight reduction of conventional al alloy end plate, and this is first advantage of the present utility model and beneficial effect place.
The utility model end plate body can use corrosion resistance and insulating properties macromolecule resin, and mix with glass fibre and strengthen the end plate main body structure, because there is not the constituent of metallics fully, so corrosion problems can not take place, this is second advantage of the present utility model and beneficial effect place.
The utility model end plate body uses macromolecule resin, and with glass fiber-reinforced structure, has good corrosion resistance, so need not to remake surface treatment, this is the 3rd advantage of the present utility model and beneficial effect place.
The utility model end plate body can use corrosion resistance and insulating properties macromolecule resin, and mix with glass fibre and strengthen the end plate main body structure, has the good insulation performance performance, so do not need to be provided with in addition one deck dielectric isolation layer, this is the 4th advantage of the present utility model and beneficial effect place.
The utility model end plate body and conducting strip are one-body molded making, known indivedual two kinds of members are combined into solid memder, but the therefore built-up time of fuel saving battery can improve the packaging efficiency of fuel cell, and this is the 5th advantage of the present utility model and beneficial effect place.
The utility model is with end plate body and the one-body molded making of conducting strip, so conducting strip can be placed in earlier in the mould of making the end plate body, tip plate configurations after completing, can there be the error of thickness distance on end plate body and conducting strip plane, and this is the 6th advantage of the present utility model and beneficial effect place.
As long as the conducting strip after the utility model punching press will not have the round side of burr, be positioned in the mould of making the end plate body, can carry out the operation of tip plate configurations compacting, therefore can save many times with leveling of conducting strip edge and removal burr, this is the 7th advantage of the present utility model and beneficial effect place.
But the above only is preferred embodiment of the present utility model, when can not be in order to limiting the enforceable scope of the utility model, allly is familiar with obviously can doing to change and modification in this skill personage, all should be considered as not departing from flesh and blood of the present utility model.
