Abstract: An inspection system of a member for a fuel cell separator including a titanium or titanium alloy base material and a coating layer including carbon includes a heater configured to heat the member for a fuel cell separator, a temperature detector configured to detect a temperature of the member for a fuel cell separator after heated by the heater, and a determination unit configured to determine a position of a high-temperature place at which a degree of a temperature increase is greater than a previously-set standard in the member for a fuel cell separator using the temperature detected by the temperature detector.

Abstract: A surface-treated titanium material for a fuel cell separator, including a titanium substrate having a passive film on a surface of the titanium substrate and a surface layer formed on the titanium substrate. The surface layer includes a titanium oxide layer and carbon particles, the carbon particles are dispersed in an inside of the titanium oxide layer, and a total film thickness of the titanium oxide layer and the passive film is 25 nm or more.
