Sealing bag for hydrogen gas, and method for dissolving hydrogen gas
The present invention aims at dissolving hydrogen gas in a liquid and maintaining the solubility of the hydrogen gas in the liquid at a high state. A sealing bag 1 that dissolves hydrogen gas in a liquid by being put into the liquid includes a hydrogen permeable film that can permeate hydrogen gas that is sealed and filled in the sealing bag to outside. By sinking this sealing bag 1 into the liquid in advance, the hydrogen gas that is permeated through the hydrogen permeable film is dissolved in the liquid. Furthermore, since the hydrogen gas is continuously permeated little by little through the hydrogen permeable film, the solubility of the hydrogen in the liquid can be maintained at a high state.
1. A sealing bag for permeating hydrogen gas comprising:
a hydrogen permeable film in a bag-like form to permeate hydrogen gas; and
a hydrogen non-permeable film partially covering the hydrogen permeable film,
wherein the sealing bag, comprising the hydrogen permeable film which is partially covered with the hydrogen non-permeable film, is filled with hydrogen gas and sealed, and the sealing bag, when provided into a liquid external to the sealing bag, is configured to dissolve the hydrogen gas into the liquid,
wherein the bag-like form has the hydrogen permeable film at opposite sides of the bag, while the hydrogen permeable film is partially covered by the hydrogen non-permeable film.
2. The sealing bag for hydrogen gas according to claim 1 , wherein the hydrogen non-permeable film does not permeate hydrogen gas or has a relatively lower permeability to hydrogen gas than that of the hydrogen permeable film.

the sealing bag comprising the hydrogen permeable film is coated with the hydrogen non-permeable film except at a permeation pore,
the permeation pore formed on the hydrogen permeable film is configured to permeate the hydrogen gas in the sealing bag to outside through the hydrogen permeable film, and
an openable and closable lid is attached to the permeation pore.
