Abstract

CéLULA DE COMBUSTìVEL E SEPARADOR DE CéLULA DE COMBUSTìVEL. A invenção refere-se a uma célula de combustível que inclui um conjunto de eletrólito, e um separador que tem uma face como uma face de formação de percurso de fluxo de gás com um percurso de fluxo de gás formado sobre a mesma para permitir o fluxo de um gás reativo e a outra face, a qual é inversa àquela face, como uma face de formação de percurso de fluxo de refrigerante com um percurso de fluxo de refrigerante formado sobre a mesma para permitir o fluxo de um refrigerante. A face de formação de percurso de fluxo de gás do separador tem múltiplos percursos de fluxo de gás lineares que estão dispostos paralelos uns aos outros, e uma estrutura de conexão de percurso de fluxo de gás que divide os múltiplos percursos de fluxo de gás lineares em grupos de percursos de fluxo de gás lineares plurais e conecta pelo menos parte dos grupos de percursos de fluxo de gás lineares plurais em série. A face de formação de percurso de fluxo de refrigerante tem múltiplos percursos de fluxo de refrigerante lineares que estão formados como uma estrutura inversa dos múltiplos percursos de fluxo de gás lineares sobre a face de formação de percurso de fluxo de gás, e uma estrutura de conexão de percurso de fluxo de refrigerante que está formada como uma estrutura inversa da estrutura de conexão de percurso de fluxo de gás sobre a face de formação de percurso de fluxo de gás para conectar os múltiplos percursos de fluxo de refrigerante lineares em paralelo.
