Abstract

Patente de Invenção: <B>"CéLULA DE COMBUSTìVEL"<D>. Uma célula de combustível, abrangendo um alojamento, ao menos uma primeira camada (1) condutora de prótons, que está coberta em ambos os lados por camadas de catalisador (5), eletrodos (2) permeáveis a gás sobre as camadas de catalisador (5) e segundas camadas (3), dispostas em ambos os lados da primeira camada (1), em forma de placas eletricamente condutoras, que tocam de modo eletricamente condutor os eletrodos (2) em distâncias vizinhas bem próximas e juntamente com os eletrodos (2) delimitam canais (4) condutores de gás, sendo que uma camada (1, 3) toca a outra camada (3, 1) com uma superfície executada essencialmente plana. Os eletrodos (2) são formados por ao menos uma camada de fibras carbonizadas de material polímero, que é atravessada em ao menos uma direção por canais de corrente se estendendo paralelamente a suas superfícies.
