応は停止する。(B) Conventional technology In a heat pump device using a hydrogen storage alloy, for example, as disclosed in Japanese Patent Publication No. 58-19955, a container filled with two types of hydrogen storage alloys is connected by a hydrogen pipe. Then, hot or cold heat is generated (heat generation process) by absorption and dissociation of hydrogen gas. Since this reaction utilizes the equilibrium pressure difference of the hydrogen storage alloy, the hydrogen gas moves from one to the other and stops when the two have reached equilibrium.

どの欠点があった。In order to reuse this, it is necessary to return to the initial state, but conventionally, the absorbed hydrogen is released again (regeneration process) by a method such as installing a heater in the alloy tank or circulating a heating medium. I was However, in these methods, it is necessary to incorporate a relatively large heat supply structure inside the container, and there are drawbacks such as an increase in heat capacity and an increase in complexity and size of the container.

必要がある。As an example, generation of freezing heat will be described. As the alloy to be used, the container 1 was filled with a rare earth-Ni-based hydrogen storage alloy 3 and the container 2 was filled with a Zr-Mn-based hydrogen storage alloy 4. The container had a long cylindrical shape and was filled with an alloy powder of 100 mesh under at a filling rate of 50%. In addition, a disk-shaped heating electrode was provided at both ends of the container. Assume that the right container is filled with hydrogen gas as an initial state, and the left container does not contain hydrogen gas. When the valve 5 is opened, the hydrogen gas moves from the right container 1 to the left container 2 through the hydrogen pipe 6 due to the pressure difference, whereby the right container 1 cools and the left container 2 generates heat. Since this reaction is stopped when the hydrogen pressure reaches equilibrium, it is necessary to return the hydrogen gas to the right container 1 in order to extract the freezing heat again.

器１はファンによって空冷した。Then, when electricity is applied to both ends of the electrode installed in the left container 2, the alloy powder is heated by the contact resistance of the powder,
By controlling the voltage and the current, the hydrogen gas was moved from the container 2 on the left to the container 1 on the right while the hydrogen pressure was kept constant, and regeneration was performed. At this time, the right container 1 was air-cooled by a fan to promote the reaction.

金の未反応部分が減少するというメリットがある。According to this method, the entire alloy is uniformly heated, as compared with the conventional heating method in which a heater or a heating medium tube is provided in a container. There is a merit that is reduced.

Electrodes 7, 7 are provided on both side ends of the container 2, and a voltage is applied from a power supply 9 by operating a switch 8.

を上昇させることができる。In FIG. 1, only the electrodes are provided inside the container 2, but in this case, a part of the current flows through the container, so that the heating efficiency is reduced. Therefore, the efficiency can be increased by coating the inner surface of the alloy container 2 with an insulator such as a Teflon coating 10 as shown in FIG. 5 so that electricity flows only between the alloy powders.

を短くして抵抗を減少させればよい。Further, depending on the particle size and filling rate of the powder, the resistance between the electrodes 7 and 7 may be too small to be heated, but in this case, in order to increase the contact resistance of the powder, an insulating powder such as alumina is used. Can be adjusted by mixing with the alloy powder. Conversely, if the contact resistance is too large, a structure combining cylindrical and rod-shaped electrodes 7, 7, etc. as shown in FIGS. 6 and 7, increases the electrode area and shortens the distance between the electrodes. Then, the resistance may be reduced.
