Document Type and Number:
Japanese Patent JP5928364
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a metal plate suitable as a separator of a polymer electrolyte fuel cell, which not only has low contact resistance, but also has excellent corrosion resistance even when exposed to a high-potential environment such as a separator use environment for a long time.SOLUTION: A surface of a metal base is coated with an Sn alloy layer film, and further a surface of the Sn alloy layer film is coated with an oxide film. Conductive particles are contained in the Sn alloy layer film, and the oxide film is of a constituent element of the Sn alloy layer film.
