MEMBRANE ELECTRODE ASSEMBLY AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is a membrane electrode assembly which enables to exhibit higher battery performance than the conventional ones in a high load region when used in a fuel cell. Also disclosed is a method for producing such a membrane electrode assembly. Specifically disclosed is a membrane electrode assembly (10) comprising an electrode (18) having a diffusion layer (14) and a catalyst layer (16) on both sides of an electrolyte membrane (12). The electrolyte membrane (12) is obtained by filling pores of a porous membrane (28) with an electrolyte (30). At least one catalyst layer (16) is formed by spraying a liquid composition containing a catalyst (20) and an electrolyte (22) for inside the catalyst layer.
