<p>A separator for fuel cell having a coating layer of gold on the surface of a metal plate and formed by plastic working wherein a relation (r+d)/r≤1.025 (50µm≤r≤100µm) is satisfied assuming the minimum bending R at a plastic working part is r (µm), and the thickness of the gold coating layer is d (µm). In such a separator for fuel cell, stripping or cracking is not generated in the gold coating layer after plastic working and corrosion resistance and durability can be enhanced remarkably.</p> |
