DEHYDROGENATION METHOD FOR HYDROGEN STORAGE MATERIALS

US,11,482,717 B2

A dehydrogenation method for hydrogen storage materials, which is executed by a fuel cell system. The fuel cell system includes a hydrogen storage material tank, a heating unit, a fuel cell, a pump, a water thermal management unit and a heat recovery unit. The described dehydrogenation method utilizes the heating unit and the heat recovery unit to provide thermal energy to the hydrogen storage material tank, so that hydrogen storage material is heated to the dehydrogenation temperature. The pump extracts hydrogen from the hydrogen storage material tank, so that the hydrogen storage material is under negative pressure (i.e. H2 absolute pressure below 1 atm), according to which the hydrogen storage material is dehydrogenated, and the dehydrogenation efficiency and the amount of hydrogen release are improved. The method n can reduce the dehydrogenation temperature of the hydrogen storage material, and reduce the thermal energy consumption for heating the hydrogen storage material.
