Abstract:
A method for determining whether a fuel cell stack cooling fluid is flowing at cold fuel cell system start-up. The method monitors the temperature of the cooling fluid outside of the fuel cell stack, and determines whether the temperature of the cooling fluid is increasing properly as the temperature of the stack increases.
