PROBLEM TO BE SOLVED: To provide a separator made of metal for a low-temperature type fuel cell excellent in acid resistance and conductivity, and suppressing the amount of Joule heat generation caused by contact resistance. SOLUTION: In this separator, stainless steel is used as a base material 15 and a plating layer 14 of Ta, Ti, or Ta-Ti having dispersed carbonous particles 13 is formed on a surface of the base material. Carbon black or graphite particles are used as the carbonous particles 13 to be dispersed in the plating layer 14. Because the separator has low contact resistance, generation of Joule heat is suppressed which causes heat loss when many cells are layered. Molding of a shape needed by a separator can be accomplished by pressing, blanking, or the like. |
