In these metal hydrides, iron-titanium hydride, lanthanum-nickel hydride, Mitsushi metal-nickel-aluminum hydride, titanium-nickel hydride,
Manganese hydride is used. The dissociation-storage equilibrium pressure difference of hydrogen in these metal hydrides is several to several tens of atmospheres at room temperature, and the equilibrium pressure increases as the temperature rises. Therefore, the hydrogen storage container must be able to withstand the maximum equilibrium pressure at the operating temperature.

る。 The metal hydride used in the present invention includes:
It is sufficient that the hydrogen dissociation equilibrium pressure or hydrogen absorption equilibrium pressure is lower than atmospheric pressure at a predetermined temperature, such as magnesium hydride, magnesium-nickel hydride,
Examples include magnesium-copper hydride, titanium-cobalt hydride, titanium-nickel hydride, lanthanum-nickel aluminum hydride, and those containing these as main components. These metal hydrides can be used as they are, but
Since its hydrogen dissociation-storage equilibrium pressure is lower than atmospheric pressure at room temperature, a container that can withstand buckling pressure must be used in that case. However, the buckling pressure is 1 atm or less at room temperature.
Furthermore, among metal hydrides, magnesium-based hydrides have a higher hydrogen storage rate per unit weight (for example, 7% by weight for magnesium hydrides) than conventional ones (2% by weight or less). Therefore, when storing the same amount of hydrogen, it is possible to use a smaller container than that using conventional metal hydrides.

In this way, for example, metal hydrides, hydrogen, etc. stored in containers etc. will not be at risk of causing chemical reactions, and deterioration of metal hydrides due to impurities such as air and moisture being forced into the container can be prevented. Furthermore, since it is possible to prevent the metal hydride from dissociating hydrogen during storage, the storage period of hydrogen can be extended.

It is used in a box, spherical, cylindrical, etc. shape.
In addition, its structure needs to withstand internal pressure in excess of atmospheric pressure, but since this excess pressure is not much different from atmospheric pressure, no special measures are required; for example, by increasing the thickness of the outer wall, etc. This can be easily resolved.

ていないことがわかつた。Example 1 A magnesium-nickel alloy is sealed in an electric furnace, the pressure is reduced to 1 mmHg or less using a vacuum pump, and then hydrogen gas is introduced at a temperature of 300°C and a pressure of about 20 atmospheres to form a magnesium-nickel hydride. The operation and the operation of releasing hydrogen at 350°C were repeated ten times. About 5% of the magnesium-nickel hydride obtained by such treatment
Kg was placed in a container modified from a commercially available 5-capacity tin can for draft beer, and while degassing from one side of the copper pipes placed in advance at two locations on the top of the container, helium gas was introduced from the other side. After reducing the internal pressure to approximately 1000 mmHg, the introduction of helium gas was stopped and both pipes were sealed. An exposure test was then conducted by leaving this product outdoors. After about 6 months, the container was opened and the contents were taken out to examine its condition and the amount of hydrogen released. As a result, the color state of the metal hydride was brownish-brown, which was the same as the state at the time of encapsulation, and there was no discoloration. Regarding the amount of hydrogen released, approximately 0.5 hydrogen gas was released per 1 g of the metal hydride. This value means a hydrogen absorption rate of 4.5% by weight, which is the same as the value when encapsulated. This revealed that the metal hydride was not altered in any way.
なお、曝露試験を自然状態下に行なつたので、
該容器は18℃〜35℃の温度範囲において直射日
光、雨などに曝され、該容器の表面最高温度は80
℃にまでなつた。 Furthermore, since the exposure test was conducted under natural conditions,
The container is exposed to direct sunlight, rain, etc. in the temperature range of 18℃ to 35℃, and the maximum surface temperature of the container is 80℃.
It got down to ℃.
