Abstract

Disclosed is a fuel cell separator (22) for separating gas between adjacent cells of a fuel battery. This fuel cell separator (22) comprises a separator base (24) made of a titanium material or a stainless steel, an oxide layer (26) formed on the separator base (24) and composed of titanium oxide or chromium oxide, and a conductive layer (28) formed on the oxide layer (26) and composed of gold (Au) or the like. The oxide layer (26) is preferably formed by oxidizing the separator base (24).
