Abstract
A method of manufacturing a fuel cell separator is provided such that the corrosion resistance can be improved. A method of manufacturing a fuel cell separator that separates adjacent cells of a fuel cell includes subjecting a separator substrate composed of a metal material to gold strike plating, thereby forming a first gold plating layer with a thickness of 10 to 200 nm. Further, thick gold plating is performed on top of the first gold plating layer formed by gold strike plating, thereby forming a second gold plating layer. A fuel cell separator manufactured by the method and a fuel cell including the fuel cell separator are also provided.
