AB - Liquid hydrogen is being explored as a potential alternative to diesel fuel in various transportation sectors, including trucks, ships, and airplanes. Fuel cells are employed to convert hydrogen into electricity; however, they produce a significant amount of waste heat. Additionally, since fuel cells utilize only gaseous hydrogen, energy is expended to vaporize liquid hydrogen into its gaseous form. By facilitating heat transfer between these two separate processes, the system’s energy consumption can be reduced. In this study, we compared diesel, gaseous hydrogen, and liquid hydrogen system with cold energy utilization. Based on these calculation results, a gaseous hydrogen fuel cell system paired with a chiller that simulated liquid hydrogen vaporizer was designed and experiments were conducted. Power consumption of the various components was measured as the fuel cell output was adjusted. The most significant parasitic loss in the standalone system was attributed to the electric heater used for vaporization. By integrating the fuel cell and liquid hydrogen vaporizer, the parasitic loss was reduced by 80 %.
