Abstract
Metal Hydride is suitable in safety and compact for decentralized fixed hydrogen storage and the boil off hydrogen collect.LaNi_<4.7>AL_<0.3> hydriding and dehydriding near normal temperature and pressure was adopted and measured basic physical properties value. Afterwards, the hydrogen storage experiment was made with changing pressure and temperature. In simultaneous experiment with charging and discharging, outflow hydrogen rate was controlled for about 3 hours by maintaining inflow hydrogen rate (0.8NL/min). Considering the hydrogen supply system to the fuel cell for 1000 families' power supply, the total energy efficiency was 76%, and effect of CO_2 reduction became 4167 kg-CO_2/day.
