Abstract

a presente invenção refere-se a uma pilha de células de combustível fs, na qual as estruturas celulares 3, cada uma das quais inclui um quadro 2 que está disposto na periferia da estrutura celular 3; e os separadores 4 que estão empilhados alternadamente, incluem um elemento de vedação s entre uma parte periférica de um quadro 2 de uma primeira estrutura celular 3 em um lado de um dos separadores e uma parte periférica do separador 4. em cada um dos separadores 4, uma primeira parte de contato 11 em contato com o elemento de vedação s, segundas partes de contato 12 em contato com um quadro 2 de uma segunda estrutura celular 3 no outro lado da mesma, e partes de conexão 13 que conectam a primeira parte de contato 11 e a segunda as partes de contato 12 estão incluídas de modo a formar uma parte de forma protuberante. cada uma das segundas partes de contato 12 inclui uma parte de fixação que fixa com o quadro. de acordo com o exposto acima, o deslocamento do separador 4 atribuído a uma carga causada por diferença de pressão ou deformação térmica é impedido de modo que a função de vedação seja mantida.
