A polymer electrolyte fuel cell material comprising a plate material (41) composed of an Fe-base alloy, Ni-base alloy, Ti or Ti-base alloy, and a cover film (44a, 44b) of a noble metal covering the surface (42, 43).The cover film (44a, 44b) on the plate ma...

An Au plating film (12) is formed on the surface of a plate-shaped metal base (13) made of a metal more base than Au, and the metal base is cut along a line of cutting plane (18) reflecting the visible outlines of a member to form a separator (10). The thu...

Disclosed is a corrosion resistant conductive part, which is made by forming a thin plated gold layer of thickness 100nm or less on a stainless steel sheet, and for which high corrosion resistance is guaranteed even with a very thin gold layer. The part is...

The present invention is to provide a free-cutting steel capable of suppressing production of coarse inclusions, and having a high fatigue strength and a desirable machinability. The free-cutting steel aimed at solving the foregoing problems consists essen...

A highly corrosion-resistant material and a corrosion-resistant member which are improved in corrosion resistance, adhesion, contact electrical resistance, electrical conductivity, airtightness, etc. and are suitable for use as, e.g., a metallic separator ...
