率の改善を試みる手段がとられていた。 By the way, when hydrogen is stored in metal powder, a large amount of heat is generated, and if this heat is not removed quickly, not only will hydrogen not be stored uniformly due to localized heat generation, but hydrogen will be generated from storage. Hydrogen is released due to the dissociation of the metal hydride, and the smooth storage reaction is significantly inhibited. In order to remove the heat generated during hydrogen storage, metal powder for hydrogen storage is conventionally housed in a tube container made of wire mesh or porous metal, and the container made of metal or porous metal is A method for removing the generated heat by bringing the storage metal into contact with hydrogen gas through a container and flowing a cooling medium around the container, or by filling small pieces of metal, stainless steel, etc. into the metal powder for hydrogen storage Steps were taken to try to improve the rate.

However, metal hydrides are ultrafine powder (5μ
(below), it is a poor conductor of heat, and since hydrogen has a small specific heat and a low thermal conductivity, the conduction speed of the generated heat is slow, making it difficult to effectively remove the generated heat.
To make matters worse, the metal powder or metal hydride has an extremely low specific gravity, so the flow of hydrogen causes the powder to move, and when the metal powder absorbs hydrogen gas, it expands and becomes dense, causing it to stick to the container wall. There is a risk that a very large stress will be applied locally, and this has the disadvantage that it becomes increasingly difficult for hydrogen gas to penetrate, and that the generated heat is more likely to accumulate, making it more likely that non-uniform reactions will occur.
このような欠点から従来の金属水素化物粉末の

The present invention is as described above, and since the hydrogen storage body is partitioned and stored in small space chambers, a large amount of heat generated when hydrogen is stored is quickly transferred into the heat medium through the walls of the space chambers. The hydrogen is removed, no local heating occurs, and the smooth hydrogen storage reaction is not inhibited. In addition, since the hydrogen storage body stored in the container is molded, there is no possibility of the powder scattering due to the flow of hydrogen, and there is no risk of localized large stress being applied to the bottom of the container. Therefore, the packing density of the hydrogen storage body can be increased.
