This paper presents the introduction condition of a passive type hydrogen storage system according to the basic hydrogen
absorption and desorption experiment using several hundred g alloys. The annealed MmNi4.6Al0.4 was selected as a hydrogen
storing material for the residential use in terms of equilibrium pressure and Plateau slope. When the hydrogen was discharged
from or charged toMmNi4.6Al0.4, the endothermic or exothermic amount was 21.7, 18.5 W per 1NL/min hydrogen
respectively. It was cleared that the hydrogen was absorbed in the condition of the ambient temperature 10～28℃ and the
absorption flow rate less than 0.2NL/(min･kg). And also, it was cleared that more than 95% of total hydrogen storage capacity
was desorbed in the condition of the ambient temperature 18～28℃, and the flow rate less than 0.34NL/(min･kg).
