によって崩れるという問題があった。It is generally known that hydrogen storage alloys such as LaNi 5 , TiFe, TiMn 1.5 , and Mg 2 Ni are pulverized by repeating storage and release of hydrogen. Therefore, conventionally, there has been a problem that even if a molded body of a hydrogen storage alloy is prepared, the molded body is collapsed due to repeated hydrogen storage / release.

The method for operating a molded body using a hydrogen storage alloy is characterized in that the molded body is molded into a shape of, and electricity is directly applied to the molded body to cause a hydrogen storage / release reaction.

実施例 以下、本発明の実施例について説明する。Examples Examples of the present invention will be described below.
まず本発明の水素吸蔵合金を用いた成形体の動作方法の
一実施例について説明する。水素吸蔵合金としてZr1.0M
n1.15Cr0.5Ni0.35合金を使用した。この合金の水素平衡

は、全体の20重量パーセントとした。First, an embodiment of the method for operating a compact using the hydrogen storage alloy of the present invention will be described. Zr 1.0 M as a hydrogen storage alloy
An n 1.15 Cr 0.5 Ni 0.35 alloy was used. The hydrogen equilibrium pressure of the alloy is 10 at 4kg / cm 2, 250 ℃ at 1kg / cm 2, 200 ℃ at 140 ° C..
It is 5 kg / cm 2 . This alloy was ground to a particle size of 100 microns or less and further coated with this alloy powder by a conventional copper electroless plating method. The coating amount of copper on the surface of the alloy powder was 20% by weight of the whole.
このようにして得た水素吸蔵合金粉末と、水素吸蔵合金

通常の水素ガスによる水素吸蔵・放出反応を繰り返し行

応ができることを確認した。The hydrogen storage alloy powder thus obtained, and commercially available alumina powder of 100 micron or less as a material having a higher electric resistance than the hydrogen storage alloy, 25% by weight of the hydrogen storage alloy powder is homogeneously mixed by a press molding method. A plate-shaped molded body having a thickness of about 2 mm was obtained. This hydrogen storage alloy molded body,
It was confirmed that the hydrogen storage / desorption reaction can be stably performed without losing the shape even if the hydrogen storage / desorption reaction is repeated by the usual hydrogen gas.
つぎにこの水素吸蔵合金成形体直接電気を通電し、通電
電気量によっての成形体自体を発させ、水素吸蔵・放出
反応を行なった結果について説明する。Next, description will be made on the result of hydrogen storage / desorption reaction in which the hydrogen storage alloy molded body is directly energized to generate the molded body itself according to the amount of energized electricity.
水素吸蔵・放出反応を行なうために密閉が可能なステン

た。A stainless steel container capable of being closed was prepared for hydrogen storage / release reactions. A pressure gauge was provided so that the pressure in this container could be detected. The above hydrogen storage alloy compact was put in this container. The hydrogen storage alloy molded body had a structure in which copper electrode lead plates for energizing were sandwiched from both ends, and a thermocouple type thermometer was provided so that the temperature of the hydrogen storage alloy molded body could be detected. Then, the inside of this container was evacuated, and then hydrogen gas was introduced so that the hydrogen gas concentration in the storage alloy was adjusted to almost fill the plateau at low temperature.

た。すなわち、目的の温度まで加熱・冷却を行なった時
いかに素早く水素吸蔵・放出反応により所定の水素平衡
圧力に達するかという点を比較した。In this way, a pulse current was passed from the external power source to the hydrogen storage alloy compact. At this time, the temperature of the hydrogen-absorbing alloy compact was raised by heat generation in a short time and a hydrogen-releasing reaction occurred to raise the pressure in the container. Next, when the energization was stopped, the temperature of the hydrogen-absorbing alloy compact was lowered due to heat dissipation, and the hydrogen-occluding reaction was caused, and the pressure in the container was lowered. The method of carrying out hydrogen absorption / desorption reaction by the amount of electricity supplied was compared with the conventional case of heating and cooling using gas or liquid and the reaction rate. That is, how quickly the predetermined hydrogen equilibrium pressure was reached by the hydrogen absorption / desorption reaction when heating / cooling to the target temperature was compared.
その結果、本実施例の水素放出反応に要した時間は約５
秒、同じく水素吸蔵反応は約10秒であった。そして本実
施例では加熱・冷却を繰り返し水素吸蔵・放出反応を約
10000回行なったが反応は非常に安定しており再現性に
優れていた。その後容器内の水素吸蔵合金成形体を外部
に取り出してみたが成形体に崩れなどの異常は見られな
かった。As a result, the time required for the hydrogen releasing reaction in this example was about 5
Second, the hydrogen storage reaction was also about 10 seconds. In this example, heating / cooling is repeated and hydrogen absorption / desorption reaction
It was performed 10,000 times, but the reaction was very stable and excellent in reproducibility. After that, the hydrogen storage alloy compact in the container was taken out, but no abnormality such as collapse of the compact was observed.
これに対し、これまでの気体や液体を用いた場合の反応
速度は加熱と冷却をいかに効率よく行なっても本実施例
の10〜12倍の時間を要した。On the other hand, the reaction rate in the case of using the gas or the liquid required 10 to 12 times as long as that of the present example, no matter how efficiently the heating and cooling were performed.
また同様の比較を水素吸蔵合金成形体に直接電気を通電
し、通電電気量によって水素吸蔵合金の水素吸蔵・放出
反応を行なうのではなく、電気ヒータと水素吸蔵合金を
接触させ電気ヒータを加熱した場合についても行なっ
た。In addition, a similar comparison is made in which electricity is directly applied to the hydrogen storage alloy compact and the hydrogen storage / release reaction of the hydrogen storage alloy is not performed by the amount of electricity supplied, but the electric heater and the hydrogen storage alloy are contacted to heat the electric heater. I also did the case.
その結果この場合は約２〜３倍の時間を要した。これは
電気ヒータによる間接加熱に起因する熱応答性の低下や
熱容量の増大が原因と思われる。As a result, in this case, it took about 2-3 times longer. This is thought to be due to a decrease in thermal response and an increase in heat capacity due to indirect heating by the electric heater.
割合などについて調べた。I checked the percentage.
このような方法にすることにより、極めて速い反応速度
を実現することが可能となった。またそれと同時に水素
吸蔵合金の水素吸蔵・放出反応の制御が容易になった。By adopting such a method, it became possible to realize an extremely fast reaction rate. At the same time, it became easier to control the hydrogen storage / release reaction of the hydrogen storage alloy.
この場合、通電電気量によって直接水素吸蔵合金の水素
吸蔵・放出反応を行なう上で、優れた成形体を得るため
に特に以下に示すような要件を満たすことが好ましい。In this case, in order to directly carry out the hydrogen storage / release reaction of the hydrogen storage alloy by the amount of electricity supplied, it is preferable to satisfy the following requirements in order to obtain an excellent molded product.
なお、使用する水素吸蔵合金として水素吸蔵合金の1kg/

Select a material with a temperature that shows the hydrogen equilibrium pressure of cm 2 from 50 ° C to 350 ° C. That is, the temperature at which the hydrogen equilibrium pressure is 1 kg / cm 2 is 50 ° C.
In the following, the hydrogen equilibrium pressure is too high, so it is somewhat difficult to control with the amount of electricity to be applied, and conversely, it is better to avoid materials of 350 ° C or higher in terms of power consumption and safety.
また、水素吸蔵合金の粉末表面を被覆する多孔質の金属

A metal oxide such as beryllia or a composite oxide thereof, a nitride such as silicon nitride or titanium nitride, a carbide such as silicon carbide, or an organic polymer such as polyimide or fluororesin is preferable. These have the function of adjusting the resistance value and the function of preventing the collapse of the molded body. Furthermore, the mixing of powdery or fibrous metal having excellent ductility and malleability is effective in improving the life of the molded body. The metal component is preferably at least one selected from Zn, Cu, Ni, Co and Cr.
