HYDROGEN PRODUCTION METHOD

摘要

One object of the present invention is to provide a method for preparing hydrogen which is able to simply produce hydrogen which is clean energy without using ammonia as used in the background art and which is very high in safety. The method for preparing hydrogen of the present invention is characterized in that hydrogen is generated by introducing mayenite (Ca 12 Al 14 O 33 ) and calcium hydroxide [Ca(OH) 2 ] into water and allowing them to react with water. Here, it is preferable that a temperature of water is from 50 to 100°C, and a molar ratio of mayenite to calcium hydroxide is 1/9.
