Abstract

A low-contact-resistance stainless steel or titanium plate for a solid polymer electrolyte fuel cell member, wherein a noble metal or an alloy of a noble metal is deposited on a portion that comes in contact with other member developing a contact resistance. The stainless steel contains not more than 30% by weight of chromium and, as required, one or more of not more than 10% by weight of molybdenum and not more than 25% by weight of nickel, these components satisfying a relationship, 10 - 0.3 x {(Cr%) + 3 (Mo%) + 0.05(Ni%)} ~ 5, and the remainder being chiefly iron. To mass-produce the solid polymer electrolyte fuel cell in a compact size, further, the invention provides a laminated module for the solid polymer electrolyte fuel cell by using the stainless steel or titanium as the constituent members.
