Abstract: To improve the efficiency of hydrogen supply for fuel cell heavy-duty trucks, a management of hydrogen supply from cryo-compressed hydrogen storage vessel to fuel cell stacks was proposed. Thermal conditions of cryo-compressed hydrogen storage and supply were numerically simulated to keep the timely evaporation of cryogenic hydrogen. The residual heat from fuel cell stacks was recycled to improve the on-board energy efficiency. Then, the supply system was designed to meet the changing requirements of cryo-compressed hydrogen, corresponding to truck loading and driving condition. The reheating power for supercritical, liquid, and gaseous hydrogen were respectively studied to keep the supply rate qualified for the fuel cell stacks. Moreover, the energy control strategies for entire system, practically the use of heat exchanger for various driving speeds were studied. Approximately, 20% of the heat generated from fuel cell stacks could be saved and the on-board energy utilisation was positively improved.
