  • Inspection system and inspection method of member for fuel cell separator
    Patent number: 11460421
    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.
