PROBLEM TO BE SOLVED: To provide a separator for a fuel cell excellent in current collecting performance in a use environment and offering no cost problem, by using a metallic material excellent in workability as a base material. SOLUTION: A separator for a fuel cell constituting a solid high-polymer type fuel cell comprises a material made by applying a coating layer composed of Sn, an Sn-containing alloy, an Sn-containing compound, RuO2 , IrO2 , MnO2 , or WC on a surface of a metallic material excellent in corrosion resistance. Because the metallic material is used as a base material, separator press forming workability is excellent and an oxide film formed on the Sn-containing coating layer during use is high in electroconductivity, and current collecting performance is prevented from lowering during use. |
