PROBLEM TO BE SOLVED: To provide a hydrogen-containing liquid generation device capable of generating a hydrogen-containing liquid with a simple operation, and a method therefor.SOLUTION: Provided is a hydrogen-containing liquid generation device comprising: a hydrogen generation agent 11 reacted with moisture to generate a hydrogen gas a first container 20 charged with the hydrogen generation agent and a second container 30 charged with a liquid L as the addition object of the hydrogen gas generated at the inside of the first container and capable of deformation at least to a direction in which volume is reduced. The first container includes: a first check valve 21 exhausting the hydrogen gas generated at the inside to the outside and a second check valve 22 or a small hole 29 introducing the liquid into the inside.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】簡単な操作で水素含有液体を生成できる水素含有液体の生成装置及び方法を提供する。【解決手段】水分と反応して水素ガスを発生する水素発生剤11と、前記水素発生剤を入れる第1容器20と、前記第1容器の内部で発生した水素ガスの添加対象たる液体Lを入れる、少なくとも容積が減じる方向へ変形することができる第2容器30と、を備え、前記第1容器は、内部で発生した水素ガスを外部へ排出する第1逆止弁21と、内部へ前記液体を導入する第2逆止弁22又は小孔29とを有する。【選択図】図1
