Stainless steels are the promising candidate materials for bipolar plate of polymer electrolyte membrane fuel cell(PEMFC)due to their high conductivity,low material and production costs,ease stamping manufacture and superior mechanical strength.However,their interfacial contact resistances(ICR)are high and corrosion resistances are not at desired levels for real PEMFC working conditions.In this study,a multi-step process including acid treatment,low temperature heat treatment and electrochemical process is employed to modify the 304 stainless steel(SS304).
