Fuel cell separator material, fuel cell, and method for manufacturing fuel cell separator material

Abstract

It is an object to provide a fuel cell separator material excellent in electroconductivity and corrosion resistance and capable of excellently adhering to a gasket material by stipulating a novel separator material, a fuel cell, and a method for manufacturing the fuel cell separator material. In a fuel cell separator material in which a carbon-based electroconductive layer including graphite is formed on the surface of a substrate formed of pure titanium or a titanium alloy, a coating rate of the carbon-based electroconductive layer is 20-70% when a range of 550×400 μm is observed with 200 times observation magnification using an electron microscope.
