14390627TOYOTA JIDOSHA KABUSHIKI KAISHANishikawa Michio

A fuel cell is used for generating driving energy for a vehicle. The reserve-tank inlet valve is located between a suction side of the coolant pump and a position in the coolant circuit at which a pressure of the coolant controlled by the reserve-tank inlet valve is an intermediate value between a discharge pressure of the coolant pump and a suction pressure of the coolant pump during an operation of the coolant pump. Even if the fuel cell is stopped generating electric power, the coolant pump is made continue operating even when the vehicle is traveling in a case that a coolant temperature exceeds a predetermined temperature. The coolant pump is made stop rotating after the coolant temperature becomes lower than or equal to the predetermined temperature. Accordingly, an occurrence of cavitation in the coolant pump is restricted at the time of restarting the fuel cell just after the fuel cell is stopped in a vehicle that is driven by the driving energy generated by the fuel cell working as a driving-energy generator.
