To continuously store/release hydrogen by heat exchange with atmospheric air, and to utilize an external heat source when the atmospheric air does not have a temperature to store/release hydrogen by a hydrogen storage alloy tank.SOLUTION: In a tank curdle A in which a hydrogen storage alloy tank 2 capable of storing/releasing hydrogen under an arbitrary atmospheric air, is housed in a housing 1, openable and closable first and second shutters 4, 5 are disposed in the upstream and downstream-side housing 1, a blower fan 8 is disposed in the housing 1, and a duct 9 connected with both end portions in a longitudinal direction of the housing 1 is disposed. When the atmospheric air temperature is within a temperature range to allow the hydrogen storage alloy tank to store/release hydrogen, the shutters 4, 5 are opened, and the blower fan 8 is operated to exchange heat of the hydrogen storage alloy tank 2 by the atmospheric air, and when the atmospheric air temperature is outside of the range, the shutters 4, 5 are closed, cold/warm water of an external heat source is introduced into the housing 1, and the cold air or warm air is circulated in the housing 1 and the duct 9 by the blower fan 8 to exchange heat of the hydrogen storage alloy tank 2.SELECTED DRAWING: Figure 2 【課題】大気との熱交換により継続的に水素の吸蔵・放出が行え、大気が、水素吸蔵合金タンクが水素を吸蔵・放出できる温度でない時は、外部熱源を利用する。【解決手段】任意の大気温度の下で水素を吸蔵・放出可能な水素吸蔵合金タンク２を筐体１内に収納したタンクカードルＡにおいて、上流及び下流側の筐体１に開閉自在な第１及び第２シャッター４、５を設け、筐体１内に送風ファン８を設け、筐体１の長手方向の両端部を接続したダクト９を設け、大気温度が、水素吸蔵合金タンクが水素を吸蔵・放出できる温度の範囲内の時は、前記シャッター４、５を開けて送風ファン８を稼働させて大気により水素吸蔵合金タンク２の熱交換を行い、大気温度が上記範囲外の時は、前記シャッター４、５を閉め、外部熱源の冷・温水を筐体１内に導入して送風ファン８により冷風又は温風を筐体１及びダクト９内を循環させて水素吸蔵合金タンク２の熱交換を行う。【選択図】 図２
