摘要： A hydrogen storage apparatus M stores a liquid hydrogen tank 1, hydrogen filling passage 3 that fills liquid hydrogen in to the liquid hydrogen tank, a degassing passage 4 provided with a relief valve V1 that opens when the pressure of hydrogen gasified in the liquid hydrogen tank reaches a predetermined level, and a hydrogen occlusive tank 2 that accommodates a hydrogen occlusive alloy 21 for storing the gasified hydrogen. When liquid hydrogen is being filled into the liquid hydrogen tank 1, the pressure in the hydrogen occlusive tank 2 is lowered using a duct 51, a cooling fan 52, and a conduit 54 for cooling the hydrogen occlusive tank 2. Accordingly, the filling time is shortened and the fuel efficiency is improved.

摘要： A method for absorbing and releasing hydrogen comprises applying repeatedly hydrogen pressurization and depressurization to a hydrogen storage metal alloy of a body-centered cubic structure-type phase exerting a two-stage or inclined plateau characteristic in a hydrogen storage amount vs hydrogen pressure relation in an appropriate fashion to absorb and release hydrogen. At least at one stage during the release of hydrogen, the temperature (T2) of the above-mentioned hydrogen storage metal alloy is made higher than the temperature (T1) of the hydrogen storage metal alloy during the hydrogen absorption process (T2>T1). This enables the release and utilization of occluded hydrogen at a low-pressure plateau region or an inclined plateau lower region.
