Abstract
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.
