ABSTRACT:
A metallic separator for a fuel cell has excellent corrosion resistance and contact resistance, even when a gold coating is applied directly without a surface treatment by a nickel coating. The metallic separator for a fuel cell, comprising stainless steel having a surface, can be obtained by coating at 2.3 to 94% of area rate on the surface without a surface treatment.
