Membrane electrode assembly for fuel cells and the manufacture method of the same

摘要

The present invention relates to a membrane electrode assembly for fuel cells and the manufacture method of the same. The membrane electrode includes at least a catalyst layer and a proton exchange membrane. At least said catalyst layer and said proton exchange membrane are applied to a porous electrically conductive sheet which conducts current to external circuit. The manufacture method of the membrane electrode assembly comprises at least the step of (A) manufacturing a porous electrically conductive sheet as substrate on which plurals of through-hole are provided; (B) applying at least the catalyst layer and the proton exchange membrane to the porous electrically conductive sheet so that every layer can contact closely with each other, and the two side of the proton exchange membrane contact at least a part of the catalyst layer. The membrane electrode assembly of the present invention have low cost, the fuel battery assembled with the membrane electrode assembly have high specific power of weight and volume and is easy to assembly and process.
