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.
Séparateur de pile à combustible et procédé de fabrication du séparateur de pile à combustible. Un premier et un second séparateur servent de séparateurs de pile à combustible. Premièrement, les deux séparateurs sont chauffés. Ainsi, une couche riche en fer est formée à la surface de chacun des séparateurs, et une couche riche en chrome d'une proportion de chrome d'au moins 60 %, est formée dans la partie intérieure de chacun des séparateurs. Ensuite, un traitement électrolytique est appliqué à chacun des séparateurs pour éliminer la couche riche en fer. Grâce à ce traitement, la couche riche en chrome est exposée à l'extérieur de la couche de surface externe de chacun des séparateurs.
