Abstract
The surface of highly conductive iron, copper, aluminum, magnesium, or alloy thereof is covered with highly corrosion-resistant titanium or titanium alloy through plastic working by rolling or extrusion to form a cladding material. At least one surface of the cladding material is covered with a carbon material to form a separator for a solid polymer electrolyte fuel cell. By virtue of the above constitution, the separator for a solid polymer electrolyte fuel cell has good workability and, at the same time, can surely maintain or improve electrical conductivity and corrosion resistance.
