Abstract
When it is detected that the temperature of the fuel cell stack is at the freezing temperature of water or less (step S), an operation mode using a freezing temperature starting up operation control map is selected (step S). Freezing temperature starting up operation of the fuel cell stack is performed according to the freezing temperature starting up operation control map (step S). Then, when it is detected that the temperature of the fuel cell stack exceeds the freezing temperature (step S), the operation mode using the freezing temperature starting up operation control map is switched to an operation mode using a normal starting up operation control map (step S). Thus, normal starting up operation is performed according to the normal starting up control map (step S).
