Please refer to Fig. 1, known a kind of fuel-cell device 100 comprises two fuel cell modules (fuel cellmodule), 110 and one cathode runner plate 120, and wherein cathode runner plate 120, shown in Fig. 2 A, is to be arranged between this two fuel cell module 110.Cathode runner plate 120 is in order to carry the required gas of cathode reaction.In known technology, can gas be flowed in cathode runner plate 120 by fan (illustrating).
Each fuel cell module 110 comprises that (wherein anode flow channel plate 114 is to be disposed between this two mea 112 to two mea for membrane electrode assembly, MEA) 112 and one anode flow channel plate 114.Anode flow channel plate 114 shown in Fig. 2 B, is in order to carry the required fuel of anode reaction.In addition, each mea 112 comprises proton exchange membrane 112a and is arranged at the anode 112b and the negative electrode 112c of proton exchange membrane 112a both sides, and the anode 112b of each mea 112 is contiguous anode flow channel plates 114.The side of each anode 112b is provided with anode collector plate 116, and the side of each negative electrode 112c is provided with cathode collector plate 118.
In known technology, the manufacture method of anode flow channel plate 114 and cathode runner plate 120 comprises two kinds of plastic rubber ejaculate molding and plastic cement die casting.With plastic rubber ejaculate molding, the thickness D1 of the thinnest part of anode flow channel plate 114 and cathode runner plate 120 is about about 0.8 millimeter (mm).With plastic cement die casting, the thickness D1 of the thinnest part of anode flow channel plate 114 and cathode runner plate 120 is about 0.25 millimeter.In addition, utilize the intensity of anode flow channel plate 114 that plastic cement die casting makes and cathode runner plate 120 to be lower than to utilize the intensity of anode flow channel plate 114 that plastic rubber ejaculate molding makes and cathode runner plate 120.
Because mea 112 needs under suitable decrement (being generally 30%), its reaction efficiency is preferred, so must bestow suitable pressure to mea 112.Also therefore, anode flow channel plate 114 must reach by force with the intensity of cathode runner plate 116, to avoid damage.In view of this, in known technology, anode flow channel plate 114 normally utilizes the method for plastic rubber ejaculate molding to be made with cathode runner plate 120.
Yet the design of fuel-cell device 100 is the trend developments towards slimming, so integral thickness D2, the D3 of cathode runner plate 120 and anode flow channel plate 114 also must dwindle.With the fuel-cell device 100 of the CD-ROM device slot that is applied to notebook computer (notebook PC), because the thickness of CD-ROM device slot is about 12.7 millimeters, so the integral thickness D2 of cathode runner plate 120 only allows in 1.4 millimeter.If cathode runner plate 120 is to be made with plastic rubber ejaculate molding, then since its thickness D1 of thin part be 0.8 millimeter, so the maximum height H of runner only is 0.6 millimeter.This will cause bigger resistance for gas flow, cause the reaction efficiency variation of fuel-cell device 100.In addition, if promote the reaction efficiency of fuel-cell device 100, and use the big and higher fan of power of size instead, then can take bigger space and expend the more energy.
In like manner, if anode flow channel plate 114 is to be made with plastic rubber ejaculate molding, it also can cause the reaction efficiency variation of fuel-cell device 100.
