PROBLEM TO BE SOLVED: To prevent a gas flow path in the fuel cell from the condensation of moisture included in the gas which blocks the flow path and prevents the reaction. SOLUTION: The fuel cell comprises an MEA10 composed of an electrolyte film 11 laid between an anode side electrode 12 and a cathode side electrode 13, and a first and a second separator 21, 22 interposing the MEA between them. The first separator has a first flow path 31 supplying fuel gas to the anode side electrode, and the second separator has a second flow path 32 supplying oxidizer gas to the cathode side electrode. A plurality of draining groove parts 41, formed so as to cross the direction of gas flow, with its one end facing a gas diffusion surface, are formed on the side walls forming the first or the second flow path, and the draining groove parts are made to absorb the condensed water generated in the flow path. |
