PROBLEM TO BE SOLVED: To provide a hydrogen production method that can easily produce hydrogen, which is a clean energy source, and has very high safety without employing a conventional method of using ammonia.SOLUTION: Hydrogen is produced by a reaction between hydrogen-substituted mayenite (CaA1O.4H) in which free oxygen in mayenite (CaA1O.2O) is substituted with hydrogen and water. In addition, hydrogen is produced by a reaction between conductive mayenite (CaA1O.4e) obtained by ultraviolet irradiation to hydrogen-substituted mayenite (CaA1O.4H) in which free oxygen in mayenite (CaA1O.2O) is substituted with hydrogen and water. |
