Abstract

Patente de Invenção: "UNIDADE DE ELETRODO DE MEMBRANA PARA CéLULAS DE COMBUSTìVEL DE ELETRóLITO POLIMéRICO E UM PROCESSO PARA A PRODUçãO DESSA UNIDADE". A invenção proporciona uma unidade de eletrodo de membrana para células de combustível de eletrólito polimérico que consiste em uma membrana de eletrólito polimérico, ambas as faces das quais estão em contato com camadas de reação porosas e camadas distribuidoras de gás. As camadas de reação contêm catalisadores de metal nobre suportados em carbono, um polímero condutor de prótons e um chamado ionómero. A unidade de eletrodo de membrana é caracterizada pelo fato de que pelo menos uma das duas camadas de reação também contém negro de metal nobre.
