Abstract
A fuel cell and a separator for same meritorious in reducing the weight and improving resistance against corrosion. In a fuel cell having a separator 2, the separator 2 includes an aluminum-based substrate 6, an intermediate plating layer layered on the aluminum-based substrate 6 and a noble metal layer 72 layered on the intermediate plating layer. The intermediate plating layer can be made up of a zinc-substitution plating layer 70 and a copper plating layer 71. The noble metal layer 72 can be a silver plating layer.
