Abstract
The present invention provides a fuel cell capable of inhibiting desiccation and flooding of a membrane electrode assembly. The fuel cell has a laminated body having a membrane electrode assembly including an electrolyte membrane sandwiched by an anode catalyst layer and a cathode catalyst layer. A pair of separators sandwiches the laminated body, and between at least one separator and the laminated body, inlet and outlet passages are formed. The inlet passage is blocked at a downstream end of the reaction gas supplied to the laminated body and the outlet passage is blocked at an upstream end of the reaction gas having passed through the laminated body. The inlet passage and the outlet passage are arranged separately from each other. The depth of the upstream region of the inlet passage is larger than that of the downstream region of the inlet passage.
