剰水素を安全に除去できる。[0008] When necessary, the apparatus is carried in and connected to the storage container. The gas containing hydrogen in the containment is blown into the reaction chamber by a blower. When the pressure in the containment vessel is high, the blower may not be provided. The reaction chamber contains a hydrogen storage alloy, which is maintained at a temperature at which hydrogen can be easily stored by the heating system and the cooling system. Gases other than hydrogen are returned to the containment vessel. Thereby, the excess hydrogen in the storage container can be safely treated. Another embodiment is shown. The configuration is the same as in the first embodiment. In this embodiment, copper oxide is used as a substance which easily reacts with hydrogen. When copper oxide is heated to 25 degrees by a heating system and hydrogen is supplied thereto, the hydrogen is oxidized to water vapor, and the copper oxide is reduced to copper. The generated steam is removed by the cooling system, and the remaining gas is returned to the containment vessel. According to this embodiment, excess hydrogen in the storage container can be safely removed.
