Hydrogen storage method, hydrogen generation method, hydrogen storage device, and hydrogen generation device

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen storage method, a hydrogen generation method, a hydrogen storage device and a hydrogen generation device. Objective. The hydrogen storage method of the present invention provides water treated so as to contain hydrogen ions in a state capable of protiumization, and a substance containing hydrogen in the water or a substance that generates hydrogen such as Mg. To store hydrogen. Preferably, the substance containing hydrogen is sodium borohydride (NaBH4). Preferably, the water is ionized hydrogen water treated with a metal hydride, and the metal hydride is at least one of an alkali metal, an alkaline earth metal, a Group 13 and a Group 14 metal. The hydrogen generation method of the present invention generates hydrogen gas from water by adding such a substance that lowers the pH of water. [Selection] Figure 1
