The invention discloses a fuel cell passenger car air-conditioning refrigerating system utilizing liquid hydrogen cold energy. The fuel cell passenger car air-conditioning refrigerating system comprises a liquid hydrogen vaporization system, a fuel cell system and a passenger car air-conditioning refrigerating system which are mutually coupled, the liquid hydrogen vaporization system is mainly used for storing liquid hydrogen and vaporizing the liquid hydrogen into hydrogen for supplying; the fuel cell system is used for carrying out hydrogen-oxygen electrochemical reaction and providing electric energy for the storage battery; the passenger car air conditioning system is used for conducting cooling liquid circulation through cold energy released in the liquid hydrogen vaporization process, and cold air is blown into a passenger car. Cooling liquid in the fuel cell passenger car air conditioning system is cooled and condensed through cold energy released in the liquid hydrogen vaporization process, an energy source is provided for refrigeration of the air conditioning system of a passenger car under the high-temperature condition, electric energy supplied to an air conditioning condensation system by a storage battery can be greatly reduced, liquid hydrogen vaporization energy is effectively recycled, and the energy utilization rate is increased. The power of a vehicle-mounted air conditioning system of the passenger car is reduced, the auxiliary power consumption of the whole vehicle system is saved, and the endurance mileage of the passenger car is increased.
