摘要： A metallic separator for a fuel cell (and a manufacturing method therefore) can reduce damage to an electrode assembly, open up the maximum capacity of the reducing effect of contact resistance due to coating of gold by gold plating or the like, and reduce consumption of gold to lower the cost. Conductive inclusions are exposed at the surface with corrosion resistance, and at least one kind of metal or an alloy thereof selected from silver, copper, nickel, and tin is precipitated on the exposed conductive inclusions. From the viewpoint of reducing contact resistance, the conductive inclusions preferably protrude from the separator surface.

摘要： The present invention relates to a fuel cell separator and a method of producing the fuel cell separator. A first separator and a second separator are provided as the fuel cell separators. Firstly, the first separator and the second separator are heated. Thus, an Fe rich layer is formed in a surface layer of each of the first separator and the second separator, and a Cr rich layer where a proportion of Cr is 60% or more is formed in an inner portion of each of the first separator and the second separator. Then, an electrolytic treatment is applied to each of the first separator and the second separator to remove the Fe rich layer. By the removal, the Cr rich layer is exposed to the outside on the outermost surface layer of each of the first separator and the second separator.
