The invention discloses a liquid hydrogen high-temperature superconducting motor full-electric propulsion system, and relates to the technical field of ships. According to the system, a liquid hydrogen storage and conveying module stores liquid hydrogen and conveys the liquid hydrogen to a power propulsion module, a hydrogen-air fuel cell power generation module and a superconducting cable power transmission and transformation module for cooling so as to ensure the working performance of each module; and the liquid hydrogen cools all the modules and then enters a heat exchanger for heat exchange to form normal-temperature hydrogen to be conveyed to the hydrogen-air fuel cell power generation module to serve as fuel, and the hydrogen-air fuel cell power generation module generates power through an electrochemical reaction of hydrogen and air and supplies power to the power propulsion module through the superconducting cable power transmission and transformation module. According to thesystem, multi-energy-state management is carried out on the whole electric propulsion system, the motor power, the motor efficiency and the energy use efficiency can be greatly improved, the ship bodyspace can be saved, the torque requirements under multiple working conditions can be met, the navigational speed, the endurance and the effective load capacity are increased in a different-emphasis mode, and self-noise and radiation noise are reduced.
