摘要: A fuel cell separator material, comprising a metal base and an Au plated layer formed on the surface of the metal base, wherein the Au plated layer has a thickness of 2 to 20 nm and arithmetic mean deviation of the profile (Ra) of 0.5 to 1.5 nm measured by an atomic force microscope within a crystal grain of the metal base.

摘要: Provided are: a separator material for a fuel cell, in which a uniform first Au-plated layer having a thickness of 0.5-4 nm is formed on one surface of a metal thin plate and a uniform second Au-plated layer having a larger thickness than that of the first Au-plated layer is formed on the other surface of the metal base material, wherein the covering rate of each of the cross-sections of the first Au-plated layer and the second Au-plated layer is 80% or more as observed on a transmission electron microscope, and which can have excellent corrosion resistance even when the thicknesses of the Au-plated layers formed on the surface of the base material are small, and can be produced at reduced cost; and a separator for a fuel cell and a fuel cell stack, each of which is produced using the separator material.
