A thermal management system of a fuel cell automobile comprises an air conditioner refrigeration cycle, a power system cooling cycle, a fuel stack temperature control cycle, an air conditioner warm air cell heating cycle, a power cell temperature control cycle and a controller, and the air conditioner refrigeration cycle is connected with the power cell temperature control cycle to dissipate heat for the power cell temperature control cycle. The air conditioner warm air battery heating cycle is connected with the power battery temperature control cycle to provide heat for the power battery temperature control cycle, and the fuel pile temperature control cycle is connected with the air conditioner warm air battery heating cycle to provide heat for the air conditioner warm air battery heating cycle. And the fuel pile temperature control cycle, the air conditioner warm air battery heating cycle and the power battery temperature control cycle are sequentially arranged nearby from front to back. Integrated design is carried out on thermal management circulation of the whole vehicle, cooling and heating requirements of parts are classified and integrated according to temperature and heat control characteristics, the circulation number in the thermal management system is reduced, thermal management of the whole vehicle of the fuel cell vehicle under different environment working conditions is achieved, and redundancy of the thermal management system is avoided.
