METHOD FOR PRODUCING FUEL CELL SEPARATOR, AND SEPARATOR MATERIAL

Provided are a method for producing a fuel cell separator, and a separator material that can prevent carbon in a carbon layer formed on the surface of a metal substrate from being detached during press forming, and thus can suppress failures in the press forming. The method is a method for producing a fuel cell separator having formed thereon gas flow channels through which fuel gas or oxidant gas to be supplied to a fuel cell stack flows, the method including preparing a plate-shaped separator material including a titanium substrate, a carbon layer covering the titanium substrate, and a resin layer covering the carbon layer; press-forming the prepared separator material into the shape of the separator such that the separator has the gas flow channels formed thereon; and removing the resin layer from the press-formed separator.
