PROBLEM TO BE SOLVED: To stably and uniformly pass a reaction gas by providing a water repellent processed layer on the inner surface of the gas passing groove of a separator. SOLUTION: A reaction gas passing groove 5 is arranged so as to be opposed to a fuel electrode 2 or an oxidizer electrode 3, and a water repellent processed layer 15 formed of gold plating layer is formed on the inner surface of the reaction gas passing groove 5. The water repellent processed layer 15 on the inner surface of the reaction gas passing groove 5 is formed of the gold plating layer, a composite layer of gold and carbon fluoride, or a fluorine resin layer such as polytetrafluoroethylene. According to such a structure, the water drops adhered to a solid polymer electrolytic film 1 by the liquefaction of the reaction gas supplied in the state humidified to the saturated water content state can be easily discharged, and the reaction gas can be stably and uniformly passed. |
