Popis: Metal hydrides are very much reported as a potential safe option for high-density hydrogenstorage materials. A combined system of proton-exchange membrane hydrogen fuel cell(PEMFC) and metal hydride (MH) tanks is designed to investigate their characteristics andperformances as hydrogen storage and stable power supply system. An AB5-type (LaCe)Ni5 material containing three MH tanks is selected for investigation. Endothermicdehydrogenation of metal hydride controls the hydrogen evolution rates during adischarging period, which reduces the risk of accidents. The MH tank charged at a20��C water bath sustains and supplies hydrogen for a longer time of 240 min. Theperformances of the MH tank at a water bath of 20��C and 10-bar conditionscorrespond to the optimum condition of hydrogen storage at the MH tank of PragmaIndustries. The performances of the combined system were investigated in differentworking conditions. The system sustains and supplies hydrogen to PEMFC for 240,160, 130, and 110 min for the working loads of 250, 500, 1,000, and 2,000 W,accordingly. It is concluded that hydrogen consumption frequency increases for higherload demand.
