Document Type and Number:
Japanese Patent JP6111058
Kind Code:
B2
Abstract:
A separator for fuel cells is provided. The separator includes: a base material; an underlying plate layer formed on the base material; and a gold plate layer formed on the underlying plate layer by means of electroless plating. The separator is characterized in that a face of the underlying plate layer facing the gold plate layer has an arithmetic average roughness Ra of 80 nm or less. According to the present invention, there can be provided a separator for fuel cells in which the gold plate layer can be uniformly formed for irregular parts that constitute gas flow channels and the occurrence of unformed parts and pinholes in the gold plate layer is prevented without increasing the film thickness of the gold plate layer and which is excellent in the corrosion resistance and the conductivity.
