PURPOSE: An indoor heating system using compressed air cooling of a fuel cell vehicle and heat generated from the compressed air cooling is provided to cool compressed air supplied to a fuel cell stack to improve the generation efficiency in the fuel cell stack. CONSTITUTION: An indoor heating system using compressed air cooling of a fuel cell vehicle and heat generated from the compressed air cooling includes an air supply system(100), a suction part(110), a blower(120), a humidifier, a stack radiator(300), a hybrid heat exchanger(500), and a heater(400). The air supply system comprises the suction part, blower, and humidifier. The suction part inhales the air. The blower compresses and blows the air inhaled by the suction part. The humidifier supplies moisture to the air compressed by the blower. The stack radiator is formed in the form of a heat exchanger. Cooling water is circulated in the stack radiator to cool a fuel cell stack. The hybrid heat exchanger is arranged between the blower and humidifier. The hybrid heat exchanger is connected to the blower and stack radiator. The hybrid heat exchanger heat-exchanges the compressed air discharged from the blower and the cooling water discharged from the stack radiator. The hybrid heat exchanger cools the compressed air and heats the cooling water.
