AIR CONDITIONING DEVICE FOR FUEL CELL VEHICLE

An conditioning device for a fuel cell vehicle includes a heater core configured to heat air in a vehicle cabin with a coolant to be discharged from a FC stack cooled by the coolant as a heat source, a coolant heating heater configured to heat the coolant, an air heating heater configured to further heat air warmed by the heater core, and a vehicle ECU configured to, in a case where a heater core outlet coolant temperature based on a target blowing temperature is equal to or higher than an FC stack inlet target temperature, perform control such that the air heating heater is operated with an output set based on the heater core outlet coolant temperature, and the coolant heating heater is operated with an output set based on a heater core inlet target coolant temperature calculated according to the set output of the air heating heater.
