Abstract

"CONJUNTO DE ELETRODO DE MEMBRANA". é apresentado um conjunto melhorado de eletrodo de membrana (10) para células de combustível de PEM, com camadas de catalisador (40, 44), respectivamente, em ambos de uma PEM de forma completamente plana (48). Camadas de difusão de gás (38, 50) são dispostas, respectivamente, sobre as camadas catalisadoras (40, 44) que não estão em comunicações com a PEM de forma completamente plana (48). Substratos porosos (32, 34) são dispostos, respectivamente, sobre as camadas de difusão de gás (38, 50) que não ficam em comunicação com as camadas catalisadoras (40, 44). Os substratos porosos (32, 34) são impregnados, nas suas periferias, com um vedante (60, 62), nas regiões que ficam em comunicação com as regiões dos substratos pororos (32, 34) impregnadas de vedante (36, 52). As camadas de difusão de gás (38, 50), os substratos porosos (32, 34) e as camadas catalisadoras (40, 44) são co-extensivas com a PEM (48).
