。Note that the above-mentioned hydrogen gas cylinders include all types of containers that store and hold hydrogen. In addition, when metal hydride repeatedly absorbs and releases hydrogen, it generally becomes fine particles of about several micrometers. Prevent them from entering the road. At the same time, the filter 9 utilizes the pressure loss when hydrogen passes through it to
Hydrogen is gradually applied at a relatively low pressure to the metal hydride in a container with a low hydrogen dissociation equilibrium pressure after hydrogen is released, thereby preventing intense heat generation due to rapid hydrogen absorption reactions and damage to the container. do. In addition to the above-mentioned connector, a valve 12 may be installed in the conduit 8 in the vicinity of the container 1o, as necessary. Needless to say, valves can be attached to the conduits as appropriate. Furthermore, although not shown, a conduit 8
It is also possible to determine the amount of hydrogen charged to the metal hydride in the container by taking a flow rate needle, especially a mass flow rate needle.

素化物に充填させることができる。Next, the drive of the vacuum pump is stopped, and the hydrogen pressure to be supplied from the hydrogen gas cylinder into the apparatus is set appropriately using the hydrogen pressure adjustment device. Practically speaking, this hydrogen pressure is 10 kg/C1δG or less, for example, 9 kg, in view of high pressure gas regulations.
/ cJ G is convenient. Hydrogen is supplied to the container for an appropriate time, and the metal hydride in the container is filled with hydrogen to a pressure of 9 kg/cJG. This operation brings the metal hydride from point B to point C. After this, the conduit 3 on the cylinder side is closed, the purge valve 5 is opened, and the hydrogen pressure in the device and container is reduced to 6 kg/ctA G.
Bring the metal hydride from point C to point. This operation
This is because the metal hydride selectively occludes only hydrogen, so impurity gas remaining in the metal hydride container without being occluded by the metal hydride is released. After this, for example,
Close the valve 12 and exhaust the inside of the device using the purge valve,
Ultimately, the hydrogen pressure inside the device is set to 0.1 to 0 less than atmospheric pressure.
．． Increase the pressure by about 5 kg/c to prevent air from contaminating the inside of the device. After this, if the connector is separated, a gold mud hydride container filled with hydrogen is obtained. By the above operation, the metal hydride in the container can normally be filled with about 7ONβ of hydrogen.

きる。As described above, according to the apparatus of the present invention, it is possible to easily fill a container filled with metal hydride with hydrogen, and in particular, the metal hydride in the container can once absorb hydrogen to a high pressure. After that, by purging and reducing the pressure, impurity gas contained in the hydrogen gas supplied from the hydrogen gas cylinder can be removed and purified hydrogen gas can be filled into the container. Containers filled with hydrogen are used for applications that require high purity hydrogen, e.g.
