| 摘要 |
This fuel cell separator (20) has a region comprising a stainless steel substrate (12a), a gold-plated layer (22) that is formed on the stainless steel substrate (12a) and has pinholes (22a), and a stainless steel passivation layer (16) formed inside the pinholes (22a), wherein the gold-plated layer (22) and the stainless steel substrate (12a) come into contact without involving the stainless steel passivation layer. This fuel cell separator (20) can be produced by forming a strike gold-plated layer on the surface of the stainless steel substrate (12) by using an acidic gold strike plating solution, then forming the gold-plated layer (22), and subsequently performing passivation treatment. The present invention provides: a fuel cell separator that has excellent corrosion resistance and that can be manufactured inexpensively, and a method for producing the fuel cell separator. |
