The fuel cell of the invention includes an electrolyte assembly, and a separator having one face as a gas flow path-forming face with a gas flow path formed thereon to allow flow of a reactive gas and the other face, which is reverse to the one face, as a refrigerant flow path-forming face with a refrigerant flow path formed thereon to allow flow of a refrigerant. The gas flow path-forming face of the separator has multiple linear gas flow paths that are arranged in parallel to one another, and a gas flow path connection structure that divides the multiple linear gas flow paths into plural linear gas flow path groups and connects at least part of the plural linear gas flow path groups in series. The refrigerant flow path- forming face has multiple linear refrigerant flow paths that are formed as a reverse structure of the multiple linear gas flow paths on the gas flow path-forming face, and a refrigerant flow path connection structure that is formed as a reverse structure of the gas flow path connection structure on the gas flow path-forming face to connect the multiple linear refrigerant flow paths in parallel.

L'invention porte sur une pile à combustible comprenant une unité d'électrolyte et un séparateur inextricablement constitué d'une surface de trajet de flux de gaz formée de trajets de flux de gaz à réaction et constitué d'une surface de trajet de flux réfrigérants formée de trajets de flux réfrigérants. La surface de trajet de flux de gaz est dotée d'une pluralité de trajets de flux de gaz linéaires formés en parallèle et d'une unité de connexion de flux de gaz permettant de diviser la pluralité de trajets de flux linéaires en une pluralité de groupes de trajets de flux de gaz linéaires et de relier en série au moins une partie des groupes de trajets de flux de gaz linéaires. La surface de trajet de flux de gaz réfrigérants est dotée d'une pluralité de trajets de flux réfrigérants linéaires inextricablement formés d'une pluralité de trajets de gaz linéaires, et d'une unité de connexion de trajet de flux réfrigérants inextricablement formée de l'unité de trajet de flux de gaz et reliant les trajets de flux de gaz réfrigérants linéaires en parallèle.
