その容積が増加し、水素を放出したときは容積が
減少する。 These alloys absorb hydrogen when cooled or pressurized and release hydrogen when heated or depressurized. Also, when these alloys absorb hydrogen, their volume increases, and when they release hydrogen, their volume decreases.
ところで、水素貯蔵容器の実用化を最も期待し
ているのは、水素のエネルギとしてのクリーン性

事故が発生するおそれがある。 As mentioned above, the hydrogen storage alloy powder increases in volume by absorbing hydrogen and decreases in volume by releasing it. However, when a car or the like runs on hydrogen, the hydrogen storage alloy powder decreases in volume by releasing hydrogen. At the same time, the vibrations of the vehicle and container cause compaction and compaction of the powder. This compacted powder has
The next time hydrogen is stored, the volume will increase in an unexpected direction or shape, which may lead to accidents such as damage to the container.
そこで、この考案の目的は、容器に振動などが

Furthermore, since the length in the piston direction increases at high temperatures, the piston is pushed and moved to reduce the volume of the storage portion for the hydrogen storage alloy powder. In this way, the piston moves while constantly applying appropriate pressure in accordance with the expansion and contraction of the hydrogen storage alloy powder, changing the storage volume.
［実施例］
以下この考案を図示の実施例について詳述す

第１図はこの考案による水素貯蔵容器の縦断面
図、第２図は第１図のＡ−Ａ断面図である。 FIG. 1 is a longitudinal sectional view of a hydrogen storage container according to this invention, and FIG. 2 is a sectional view taken along line A-A in FIG.

横置円筒形容器１には、水素を送入又は放出する
管またはノズル２が設けられ、これに閉止弁３が
設けられている。 A horizontal cylindrical container 1 made of a suitable material such as metal or FRP is provided with a pipe or nozzle 2 for supplying or discharging hydrogen, and is provided with a shutoff valve 3.

４を圧しつけている。 The hydrogen storage alloy powder 4 is contained in a predetermined space 4 with respect to the nozzle 2 by an air permeable mesh 5 and a piston 6 provided with ventilation holes. The piston 6 is slidable in the axial direction of the cylindrical container while storing the powder 4 in the space 4 . Further, the piston 6 is pushed by the elasticity of two U-shaped bimetals 7 whose bottoms are fixed to the part of the container 1 that does not contain the powder 4 (non-storage part), and presses the powder 4 with an appropriate pressure. ing.
バイメタル７は、温度が高くなるとＵ字形の口

金属を貼り合わせたものであり、かつ、弾性変形
にもとずく反力を発生する役割も果たす。 Bimetal 7 is made by bonding different metals together so that it opens a U-shaped opening when the temperature rises and closes when the temperature drops, and also plays the role of generating reaction force based on elastic deformation. .

容することができる。 To store hydrogen in this container 1, hydrogen is injected through the nozzle 2 and the container is cooled at the same time. The hydrogen storage alloy powder 4 in the container absorbs hydrogen and increases its volume. At this time, as mentioned above, the bimetal 7 deforms to close its mouth due to the decrease in temperature, so the hydrogen storage alloy powder 4 absorbs hydrogen and increases in volume. Since the movement of the piston 6 accompanying the volume increase is not hindered and there is a reaction force due to elastic deformation, the volume of the hydrogen storage alloy powder 4 can be increased while being subjected to appropriate pressure.

The volume reduction due to hydrogen release follows the volume reduction of the hydrogen storage alloy powder 4 while assisting the movement of the piston 6 by opening the mouth of the bimetal 7 due to temperature rise and applying reaction force due to elastic deformation.

変化させることができる。 If the amount of deformation of the bimetal 7 is determined in relation to the change in the volume of the hydrogen storage alloy powder 4, the compressive force can be applied to the hydrogen storage alloy powder 4 within a certain range, and the amount of deformation can be determined in relation to the change in the volume of the hydrogen storage alloy powder 4. Therefore, the volume of the storage chamber can be changed.
なお、バイメタルの代わりに、空気ばね、ばね

ことができる。[Effects of the invention] As explained in detail above, according to this invention, while applying a certain range of pressure to the hydrogen storage alloy powder stored in the hydrogen storage container, the volume of the storage chamber is changed according to changes in the container. Since it is possible to change the hydrogen storage alloy powder, compression and compaction of the hydrogen storage alloy powder can be prevented even if vibration or the like is applied to the container. As a result, absorption and release of hydrogen is performed smoothly, damage to the container is prevented, and it is possible to contribute to the practical use of hydrogen energy using hydrogen storage alloy powder.
