ABSTRACT:
A metal composite for use in electrochemical devices is disclosed. The metal composite comprises a stainless steel interior component and a deposited nitrided metal exterior layer, wherein the nitrided exterior layer has lower electric contact resistance and greater corrosion resistance than the stainless steel interior component. A bipolar plate made of such metal composite and methods of producing the metal composite and bipolar plate are also disclosed.
