    Abstract: In a vehicle air conditioner where air blown into a passenger compartment is heated in a heater core using cooling water for cooling a fuel cell system as a heating source, a flow amount of cooling water flowing into the heat core is controlled by a control valve based on a surplus heat quantity of the fuel cell system and a necessary heat quantity of the passenger compartment. Further, when the surplus heat quantity of the fuel cell system is smaller than the necessary heat quantity, an insufficient heat quantity is supplemented by a supplementary heater.
