摘要:
Provided is a fuel cell separator that can maintain a low contact resistance for a long period of time while being used for a fuel cell, by using a carbon film that can be formed with high productivity. The fuel cell separator 10 is provided with: a substrate 1 comprising titanium or titanium alloy; and a conductive carbon layer 2 that is formed by compression bonding carbon powder onto the substrate 1, and covers the surface thereof. Between the substrate 1 and the carbon layer 2, particle-like titanium carbide 31 and carbon dissolved titanium 32 generated by reacting the titanium of the substrate 1 and carbon of the carbon layer 2 with each other through heat treatment are connected, forming an intermediate layer 3.
