PURPOSE:To reuse hydrogen gas used for hydrogen treatment effectively with no ejection to outside. CONSTITUTION:Hydrogen gas stored in a hydrogen storage alloy storing device 4 is used for a hydrogen treatment, in which a material absorbs hydrogen gas and then ejects it, and after the treatment the ejected used hydrogen gas is stored again in the hydrogen storage alloy storing device 4, a then the hydrogen gas is ejected again to reuse for the hydrogen treatment. |
