Abstract

a presente invenção refere-se a uma pilha de célula de combustível que inclui unidades de célula e separadores que são alternadamente empilhados, na qual cada uma das unidades de célula inclui uma célula única. cada um dos separadores inclui: pelo menos uma primeira crista que é disposta em uma primeira superfície principal de cada um dos separadores em um intervalo predeterminado para formar pelo menos um primeiro canal de gás; e pelo menos uma segunda crista que é disposta em uma segunda superfície principal de cada um dos separadores em um intervalo predeterminado para formar pelo menos um segundo canal de gás. a pelo menos uma primeira crista e a pelo menos uma segunda crista são dispostas em um intervalo regular ao redor de um centro de cada um dos separadores em um corte perpendicular ao primeiro ou segundo canal de gás. a pelo menos uma primeira crista e a pelo menos uma segunda crista dos separadores são dispostas, tal que uma primeira crista e uma segunda crista de um primeiro separador de dois dos separadores mantendo cada unidade de célula pelo menos parcialmente sobrepõem respectivamente com uma segunda crista e uma primeira crista de um segundo separador dos dois dos separadores em uma direção de empilhamento dos separadores através de uma célula única colocada entre os dois dos separadores.
