Abstract:
A method of depositing a metal having corrosion resistance on a separator for a fuel cell, the method comprising the steps of projecting to a separator of a unit cell for forming the fuel cell, the separator being made of a metallic material with a passivation film on the surface, a solid plating material comprised of hard metal core particles having a higher hardness than the separator and coated with a metal having corrosion resistance and carbon contact resistance of not more than 20 m&OHgr;Â·cm2 at a contact pressure of at least 1 kgÂ·f/cm2 so as to destroy the passivation film and to compulsorily deposit the metal coated on this solid plating material to the separator.
