Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent occurrence of cavitation which may occur in a cooling water pump 1, when a fuel cell is restarted immediately after being stopped, in a vehicle traveling with the energy of the fuel cell 2 serving as a drive energy generation device.SOLUTION: There is provided a fuel cell 2 for generating energy used to cause a vehicle to travel. A reserve tank inlet valve 10 is arranged in a position slightly nearer to an intake side of a cooling water pump 1 than a position of a cooling water circuit where pressure of cooling water controlled by the reserve tank inlet valve 10 adopts a middle value between discharge pressure of the cooling water pump 1 during driving and the intake pressure of the cooling water pump 1. Even when the fuel cell 2 stops generating power, when the temperature of the cooling water exceeds a predetermined temperature as in steps S62 and S63, the cooling water pump 1 is kept rotating even while the vehicle is traveling. The rotation of the cooling water pump 1 is stopped after the temperature of the cooling water has fallen at least to the predetermined temperature.
