Abstract

CéLULA DE COMBUSTìVEL, E, PILHA DE CéLULA DE COMBUSTìVEL Uma célula de combustível incluindo uma montagem de membrana-eletrodo tendo uma face de eletrodo de anodo; uma placa de anodo adjacente a dita face de eletrodo de montagem de membrana-eletrodo e acoplada a ela por uma gaxeta de vedação. A gaxeta de vedação, face de eletrodo e placa de anodo juntas definem um volume de contenção de fluido para entrega de fluido de anodo à face de eletrodo. Uma folha de material de difusor poroso está situada no volume de contenção de fluido e tendo pelo menos um espaço definido entre pelo menos uma borda lateral da folha de material de difusor e a gaxeta de vedação. Fluido para entrega a uma superfície ativa da montagem de membrana-eletrodo pode ser entregue pelo espaço e por difusão pelo material de difusor a uma tal extensão que canais de fluxo de fluido na placa de anodo não são requeridos.
