いる。When hydrogen storage alloys are used in heat pumps, etc., the conventional alloy activation treatment method used to activate the hydrogenation reaction is to place pre-pulverized alloy powder in an actual reaction vessel (
A common method is to fill a heat pump, etc.) and activate it at several times the normal pressure. Therefore, in the conventional activation treatment method, the treatment is carried out at a pressure several times that of normal operation, so that the wall thickness of the actual damaged reaction vessel becomes thicker than necessary, and the heat exchange of reaction heat cannot be carried out quickly. This significantly delays the hydrogenation reaction in actual equipment and increases the cost of manufacturing the actual equipment, which is considered to be one of the major factors preventing the practical use of hydrogen storage alloys.

The purpose of the present invention is to propose a hydrogen storage alloy activation treatment method and apparatus that can increase efficiency.
