Title:
MATERIAL FOR FUEL CELL SEPARATORS AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2014/119443
Kind Code:
A1
Abstract:
Provided are: a material for fuel cell separators, which has excellent adhesion between a base and a carbon layer, excellent conduction durability and excellent production efficiency; and a method for producing the material for fuel cell separators. A method for producing a material for fuel cell separators, which comprises: a coating step wherein a coating layer that contains carbon and a binder compound containing a carbon atom and an oxygen atom is formed on the surface of a titanium base that is formed of titanium or a titanium alloy and has a thickness of 40-200 μm; and a heat treatment step wherein the titanium base covered with the coating layer is subjected to a heat treatment. This method for producing a material for fuel cell separators is characterized in that: the titanium base covered with the coating layer is wound into a coil shape and then subjected to a heat treatment; the heat treatment is carried out in a vacuum atmosphere of 10 Pa or less; and a carbon layer and an intermediate layer containing titanium carbide are formed from the coating layer in the heat treatment step.
