費用も高価となる。However, when metal hydrides such as those mentioned above are taken out into the atmosphere as they are from an active state in a hydrogen atmosphere, the surface of the metal hydride may rapidly oxidize, generate heat, and ignite. . Therefore, for example, when disposing of a container filled with metal hydride, it is dangerous to take out the metal hydride inside the container into the air without performing any inactivation treatment. When removing metal hydride from a container, conventionally, hydrogen is removed from the container filled with metal hydride under reduced pressure and then water is poured into the container to prevent the metal hydride from generating heat. . However, such a method is not only complicated but also expensive.

とは、上記のように活性な金属水素化物からその活性を
失わしめることをいう。In the present invention, the active metal hydride refers to a metal hydride that is typically in a hydrogen atmosphere and has the ability to absorb and release hydrogen. When the metal hydride is active, the metal hydride absorbs this hydrogen by filling the container with hydrogen under pressure, as shown by the solid line in the drawing. The hydrogen pressure inside the tank decreases. Moreover, if the pressure inside the container is reduced from such a state, the metal hydride releases hydrogen. On the other hand, as shown by the broken line in the drawing, inert metal hydrides do not absorb hydrogen even if the container is filled with hydrogen under pressure, so the hydrogen pressure inside the container does not change. Inactivation of a hydride means to make an active metal hydride lose its activity as described above.

性を回復しない。In the present invention, the metal hydride can be reversibly or irreversibly inactivated depending on the amount of the halogen-containing substance brought into contact with the metal hydride. That is, when a metal hydride is inactivated by contacting with a halogen-containing substance in an amount of about 0.001 to 1% by volume of the total amount of hydrogen it can store, the metal hydride is usually activated by a conventional method. By doing this, the activity will be restored again. On the other hand, when a metal hydride is inactivated by contact with a halogen-containing material in an amount greater than about 1% by volume of the total amount of hydrogen it can store, the metal hydride is irreversibly inactivated. However, the activity is usually not restored even after subsequent activation treatment.

It can be similarly inactivated by Metal hydrides inactivated in this way do not generate heat or ignite even when taken out into the air.
