<P>PROBLEM TO BE SOLVED: To provide a metal separator for a fuel cell having sufficient corrosion resistance even if with thin noble metal plating thickness for reducing contact resistance of stainless steel, to provide its manufacturing method, and to provide a metal plate with a noble metal plated for the separator. <P>SOLUTION: This separator for a fuel cell has a noble metal layer on a surface of this metal plate, and is characterized by using the noble metal-plated metal plate for which the noble metal layer is sealed by one or more kinds of mercaptobenzothiazole derivatives, as an inhibitor, expressed by formula (1), wherein R1 is hydrogen, alkyl, substituted alkyl or halogen; R2 is an alkaline metal, hydrogen, alkyl, substituted alkyl or a substituted amino group. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
