In order to increase the speed of storing and releasing hydrogen, an alloy-filled layer is required in the storage of hydrogen.

ル部では熱媒管が挿入しにくいという問題があった。The heat exchanger used in the method for promoting heat transfer and improving thermal efficiency by moving the hydrogen storage alloy between containers (Japanese Patent Application No. 08-056562) has a plurality of internal heat exchangers. This is a heat exchanger in which the heat transfer tubes are arranged in parallel, and a vibrator is installed to promote uniform movement of the hydrogen storage alloy. On the other hand, the use of a heat exchanger structure in which the commonly used internal heat transfer tubes are installed in parallel makes it possible to promote a uniform drop when the hydrogen storage alloy comes into contact with the surface of the heat transfer tubes due to the drop. Therefore, even when vibration is applied, there is a problem that the lower surface of the heat medium pipe surface is not effectively contacted and the heat exchange area is not effectively used. In addition, since the hydrogen storage alloy has poor fluidity, there is a problem that it is difficult to insert a heat medium pipe in the conical portion of the discharge portion.
