Provided is a method for producing a metal separator plate for a fuel cell having outstanding corrosion resistance and electrical conductivity not only initially but also even after long-term use in a fuel-cell operating environment. The method for producing a metal separator plate for a fuel cell according to the present invention comprises the steps of: preparing a stainless steel plate parent material; forming a non-continuous coating film of at least one of gold (Au), platinum (Pt), ruthenium (Ru), iridium (Ir), ruthenium oxide (RuO2) and iridium oxide (IrO2) on the surface of the stainless steel plate parent material; and subjecting the stainless steel plate, on which the non-continuous coating film has been formed, to a heat treatment and thereby forming an oxide film on the area where the coating film was not formed. Also provided is a metal separator plate for a fuel cell having a coating film formed on the surface, produced by means of the method. |
