−１４９１−０１号、同５５−１４９１０２号公報）。Normally, these alloys are used alone, but a method has been proposed in which two or more alloys are mixed together in order to obtain an arbitrary hydrogen equilibrium pressure depending on the purpose of use (Japanese Patent Application Laid-Open No. 1983-1992).

There is an invention described in Japanese Unexamined Patent Publication No. 59-2], No. 1.543.

と同様に速い。On the other hand, FeTi alloy is considered to be the most promising in the future in terms of price and performance. This FeTj alloy has a reaction rate of L, Ni5, MmN]45Ani0.5 after hostification treatment to enable the alloy to react with hydrogen.
Just as fast.
しかしながら、活性化処理として、４００−Ｃ以上の高
温で真空、次いで室温で３０ Ｋｇ／ｃａ以上の高圧水
素処理の操作を、約１時間サイクルで約１週間という長
期間多数回くり返す必要があり、実用的に非常に不都合
であった。However, as an activation treatment, it is necessary to repeat the operation of vacuum treatment at a high temperature of 400-C or higher, followed by high-pressure hydrogen treatment of 30 Kg/ca or higher at room temperature, many times over a long period of about 1 week in a cycle of about 1 hour. , which was extremely inconvenient from a practical standpoint.
この活性化性能を改善する目的で、Ｆｅの一部をＮｂ、
ＭｎあるいはＴ１で置換する方法、あるいは酸化物を合
金中に分散させる方法が見い出された。In order to improve this activation performance, some of the Fe was replaced with Nb,
A method of substituting with Mn or T1, or a method of dispersing an oxide in the alloy was found.

Ｔ１で置換する場合や酸化物を分散させる場合では水素
解離平衡圧のプラトー性が悪くなったり、水素放出量が
減少するなどの欠点ヶ生ずる。Addition of these elements improves activation performance, but the method of replacing with Nb is expensive, and when replacing with Mn or T1, or when dispersing oxides, the hydrogen dissociation equilibrium pressure may plateau. This results in disadvantages such as deterioration of hydrogen performance and a decrease in the amount of hydrogen released.

, or by adding Mm (Mitushmetal) to 80~
We have developed an alloy that can be activated at 100°C or room temperature and has good plateau properties.

向があった。However, when adding s2, a temperature of 80 to 100°C is required, and when adding Mm,
Although it is lower in cost than the alloys developed so far, it tends to be somewhat more expensive than FeTi due to the addition of Mm, which is also somewhat more expensive than FeTi.

The release operation was repeated until no change in the amount of hydrogen storage was observed, and then the hydrogen storage was examined. The reaction rate varies depending on the sample weight, container shape, etc., but in order to obtain relative values for each alloy, the reaction was carried out using the same sample container with the same weight of alloy powder of ], 09. The reaction rate was expressed as SO% of the maximum hydrogen storage capacity of each alloy, and the time (minutes) required to store hydrogen up to 90%.
