PROBLEM TO BE SOLVED: To provide an electrode for a fuel cell which has a long life and a light weight at low cost. SOLUTION: The electrode for a fuel cell is prepared by forming an under Ni plating layer, a surface rhodium plating layer and an electric potential difference reducing plating layer between the Ni plating layer and the Rh plating layer. A corrosion of aluminum or magnesium by an electrolyte of the fuel cell can be prevented by a high anti-corrosive Rh layer, A diffusion of the Rh can be prevented by the Ni plating layer. Electric potential difference between the Ni plating layer and the Rh plating layer can be reduced by the potential difference reducing plating layer to prevent a corrosion caused by the potential difference. |
