Abstract:
1. A method of manufacturing a fuel cell separator that separates adjacent cells of a fuel cell, the method comprising: subjecting a separator substrate comprising a metal material to gold strike plating, thereby forming a first gold plating layer having a thickness of 10 nm to 200 nm, wherein the gold strike plating is conducted at a current density of 0.2 to 2 A/dm performing additional gold plating on top of the first gold plating layer formed by the gold strike plating, thereby forming a second gold plating layer having a thickness of 100 nm to 20 μm, wherein the gold concentration for the gold strike plating is lower than that for the additional gold plating, and wherein the separator substrate is molded from titanium or stainless steel and is subjected to at least one of a cleaning treatment and an acid washing treatment.
