摘要：
A metallic separator for fuel cells having a metal plate, an electroconductive coating layer covering at least a surface in front and back surfaces of the metal plate which contacts a raw material and/or a reaction product, and an electroconductive channel-forming member disposed on a surface of the coating layer and forming a channel for the raw material and/or the reaction product and/or a channel for a cooling medium for cooling. A surface layer on the metal plate has a tensile residual stress within such a range that no stress-corrosion cracking occurs.
