POWER SUPPLY APPARATUS FOR VEHICLE

A power supply apparatus for a vehicle includes a fuel cell, an air conditioner condenser, an electrical system radiator, a fuel cell radiator, and a compressor. The air conditioner condenser is disposed in a first circuit of a refrigerant used for air conditioning of a passenger compartment of the vehicle. The electrical system radiator is disposed in a second circuit of a refrigerant used for cooling of in-vehicle electric devices other than the fuel cell. The fuel cell radiator is disposed in a third circuit of a refrigerant used for cooling of the fuel cell. The compressor is disposed in an air passage coupled to the fuel cell and introduces air to the fuel cell through the air passage. One or both of the air conditioner condenser and the electrical system radiator are disposed upstream of the compressor in the air passage.
