The invention discloses a temperature control system for a hydrogen fuel cell vehicle, and belongs to the technical field of thermal management systems of hydrogen fuel cell vehicles. The invention discloses a temperature control system for a hydrogen fuel cell vehicle. The temperature control system comprises a passenger compartment heating and circulating system, a battery heating circulating system and a battery pack cooling circulating system, the passenger compartment heating circulation system comprises a cooling liquid loop I and a cooling liquid loop II which are connected in parallelthrough a water heat exchanger. The battery heating circulation system comprises a cooling liquid loop III, and the two ends of the battery heating circulation system are connected to the cooling liquid loop III in parallel through a water valve and a three-way valve respectively. The passenger compartment refrigeration cycle system comprises a refrigerant loop I, and the battery pack cooling cycle system comprises a refrigerant loop II and controls the loops to be closed through a first electronic expansion valve and a second electronic expansion valve respectively. All the temperature control systems are in loop connection, so that the temperature control system has the advantages of simple and compact structure, convenience in installation, complete functions and the like.
