Description
Technical field
The present invention relates to a kind of core component and reach the membrane electrode of preparation thus with sealed frame.
Background technology
Ion-exchange membrane fuel cell (PEMFC) has high power density; high-energy conversion efficiency; cold-starting; advantages of environment protection; promise to be most the power source of zero disposal of pollutants electric car; make it in today that global energy crisis and environment go from bad to worse, become one of focus of international new and high technology competition.Membrane electrode (MEA) is the most key assembly of ion-exchange membrane fuel cell generating, mainly form by two good porous gas diffusion layer of conductivity and one deck amberplex that is clipped in the middle, on the interface on amberplex and gas diffusion layers both sides, be evenly distributed with the catalyst of the caused electrochemical reaction of a large amount of tiny dispersions, hydrogen/methyl alcohol etc. evenly spread to catalyst surface generation electrochemical reaction through relative gas diffusion layers respectively with oxygen/air, the electronics that produces in the electrochemical reaction is drawn the forming circuit loop by conductor by external circuit.
Amberplex in the ion-exchange membrane fuel cell plays proton conducting, and intercept electronics and directly constitute the loop at inside battery, and the effect that directly contacts of blocking-up hydrogen/methyl alcohol etc. and oxygen/air.In order to reduce the resistance of proton conduction, in the ion-exchange membrane fuel cell field, general in the world used thickness is especially preferentially selected the amberplex of thickness less than 30 μ m less than the amberplex of 50 μ m.Simple use this extremely thin amberplex and when not adopting other encapsulant, at gas percussion, can cause all in the Battery holder process that sealing effectiveness is bad, hydrogen/methyl alcohol etc. directly contact with oxygen/air and influence output performance, even the danger of blast occurs.The encapsulating method that adopts is diverse trends at present, makes the preparation process of membrane electrode various method also occur.
[US3134697, EP700108A2] introduced a kind of membrane electrode, and its amberplex size is greater than gas diffusion layers, and when membrane electrode during in sealing, the amberplex that exceeds gas diffusion layers is sandwiched between the battery pole plates.Also the amberplex that exceeds gas diffusion layers can be clipped between other the seal.This mechanical damage that in assembling, very easily causes film by thickness less than the amberplex of 30 μ m.In use, amberplex very easily is subjected to humidity effect and the change of size, the further mechanical damage of aggravation film takes place.
[CN200480030791.7] introduced a kind of core component and membrane electrode with encapsulant.It adopts thermoplastic polymer, elastic sealed body and thermosetting polymer is encapsulant.There is the encapsulant protection at the edge of amberplex, and gas diffusion layers all adopts encapsulant that negative electrode and anode reactant are completely cut off, and this method can obtain better seal.All adopting the thermoplastic polymer polyamide among embodiment 1 and the embodiment 2 is encapsulant, adopts the mode of hot pressing to make encapsulant and amberplex be combined into an integral body.[CN200380105886.6] introduced a kind of MEA, and amberplex and gas diffusion layers bond by thermoplastics.In the embodiment of this patent, introduced, the mode of thermoplastics by hot pressing has been injected in the gas diffusion layers, amberplex and gas diffusion layers have been bonded to an integral body by the thermoplastics that penetrates in the gas diffusion layers.The embodiment of this patent is the MEA that is told fully by the distributed heat compacting, and every hot pressing all needs a few minutes, and manufacture craft is complicated.
[US6057054] introduced a kind of membrane electrode, and it penetrates into encapsulant in the gas diffusion layers and seals, and encapsulant can extend to outside the gas diffusion layers.Encapsulant can have rib shape and cross rib shape pattern.
[US6261711] introduced the sealing ring of fuel cell, and the sealing ring that fuel cell comprises is positioned at the groove of fuel cell flow field board.
For commercial prod, excellent sealing performance is no doubt important, but can adapt to the method no less important of mass production.Therefore we not only are devoted to study the encapsulant that is suitable for ion-exchange membrane fuel cell, are devoted to study the technology that is applicable to batch process simultaneously.
