Fuel cell separator and fabrication method thereof, and conductive corrosion-resistant metallic material

摘要

A fuel cell separator is provided with: a core made of an Al alloy or a Mg alloy; a covering layer made of Ti or a Ti alloy formed on at least one side of the core; and a bonding metal layer formed between the core and the covering layer. The bonding metal layer is made of a metal with a deformation resistance lower than the core and the covering layer.
