Method of generating hydrogen

摘要

A catalyst has a long life span and efficiently separates hydrogen from water. A first metal element (Ni, Pd, Pt) for cutting the combination of hydrogen and oxygen and a second metal element (Cr, Mo, W, Fe) for helping the function of the first metal element are melted in alkaline metal hydroxide or alkaline earth metal hydroxide to make a mixture heated at a temperature above the melting point of the hydroxide to eject fine particles from the liquid surface, bringing steam into contact with the fine particles. Instead of this, a mixture of alkaline metal hydroxide and metal oxide is heated at a temperature above the melting point of the alkaline metal hydroxide to make metal compound in which at least two kinds of metal elements are melted, and fine particles are ejected from the surface of the metal compound to be brought into contact with steam.

主权项

1. A method of generating hydrogen from water which comprises the steps of:
a) accommodating an alkaline metal hydroxide and a metal element supply body in a sealable case so as to form a reaction space above the alkaline metal hydroxide; b) heating the case to a temperature above a melting point of the alkaline metal hydroxide so as to make a molten salt; c) melting each element of the metal element supply body into the molten salt; d) ejecting a large number of fine particles including elements of the metal element supply body from a surface of the molten salt into the reaction space; and e) supplying steam into the reaction space without passing through the molten salt to react with the fine particles while airflow into the reaction space is prevented.
