The invention discloses an ORC-based fuel cell cold chain vehicle liquid hydrogen cold energy utilization system and method. The system comprises a fuel cell coolant circulation loop, an ORC working medium circulation loop and a liquid hydrogen circulation loop which are mutually coupled. The invention designs a fuel cell cold chain vehicle liquid hydrogen cold energy utilization system, and a fuel cell cooling system and a cold chain vehicle refrigeration system are improved; based on the designed fuel cell cold chain vehicle liquid hydrogen cold energy utilization system, the cold energy of liquid hydrogen can be utilized for power generation, and the hydrogen consumption of a cold chain vehicle is reduced; the heat exchange of the PEMFC coolant with the ORC working medium and the hydrogen stream can absorb the heat of the fuel cell stack, reducing the load of the fuel cell cooling system, and reducing the total parasitic power of the fuel cell system.
