ABSTRACT:
In starting power generation under low temperature conditions, an antifreeze liquid being coolant of a cooling system in a fuel cell stack is once recovered in a tank to reduce heat capacity of the fuel cell stack, and thereafter the power generation is started. Heat of reaction caused by the power generation restores the temperature to temperature under normal operation, and then the antifreeze liquid is again filled to drive the cooling system, so as to make it function as a cooler.
