PROBLEM TO BE SOLVED: To provide a simple and safe hydrogen gas generation, an inhalational method and its device in which a hydrogen gas is made to permeate a high quality water filter being transparent and unscented in the generation thereof, and hydrogen gas molecules are activated by underwater metal ions to send the hydrogen gas to the body of an inhaler.SOLUTION: A skeleton type hydrogen gas generator is characterized as follows: a hydrogen gas generating material comprising a base material A obtained by mixing powder calcium oxide with powder aluminum and a preparation reaction acceleration material B of an inorganic salt compound or a hydrogen generation promotion admixture C is put in a permeable bag 1 the bag 1 is immersed in water or warm water received in a large size container comprising a lower container 3 and an upper container 4 being sealed and transparent, and an anhydrous citric acid 9 is added in the water or warm water a ratio of the hydrogen gas generating material to the water or warm water of 1,000 cc is 10-25 g and the ratio of the anhydrous citric acid to the same is 0.3-1.6 and thereby the hydrogen gas is generated in the sealed large size container, and the hydrogen gas is inhaled through a tube derived from the large size container.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】水素ガスの発生において、透明で無臭である良質な水フィルタを透過させ、水中の金属イオン等により水素ガス分子を活性化させて水素ガスを吸入者の体内に送る、簡易で安全な水素ガス発生、吸入方法及びその装置を提供する。【解決手段】粉体酸化カルシウムと粉体アルミニウムを混合させた基盤材Aと、無機塩化合物の調合反応促進材B又は水素発生促進混合材Cとから成る水素ガス発生材を透水性の袋1に入れ、当該袋1を、密閉された透明な下部容器3及び上部容器4から成る大容器に入った水又は温水に浸漬するとともに、当該水又は温水に無水クエン酸9を添加し、前記水又は温水1000ccに対して、水素ガス発生材を10~25g、無水クエン酸を0.3~1.6の割合とし、前記密閉された大容器内で水素ガスを発生させ、当該大容器から導出した管を介して水素ガスを吸入する。【選択図】図5
