Catalyst for generating hydrogen, method of generating hydrogen and apparatus for generating hydrogen
View Patent ↗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.
1. A catalyst cell for generating hydrogen from water, comprising:
a sealable casing;
a source of an alkaline metal hydroxide of sodium hydroxide (NaOH) or potassium hydroxide (KOH), said alkaline metal hydroxide being contained within the casing;
a metal element supply body comprising at least two different metal elements, the metal elements selected from the group consisting of nickel (Ni), palladium (Pd) and platinum (Pt) as a first metal element, and selected from the group consisting of chromium (Cr), molybdenum (Mo), cobalt (Co), copper (Cu), rhodium (Rh) and tungsten (W) as a second metal element;
a heating device configured to heat the alkaline metal hydroxide contained within the casing to a temperature above the melting point of the metal hydroxide so as to form a molten metal hydroxide salt;
a sealable reaction space formed above said molten metal hydroxide salt, the reaction space configured to prevent airflow when sealed, said metal element supply body being contained within the reaction space; and
a supply of steam to the reaction space;
the catalyst cell being configured to eject fine particles of the molten metal hydroxide salt from a liquid surface of the molten salt into the sealed reaction space, said metal hydroxide fine particles reacting with the steam in cooperation with the at least two metal elements supplied by the metal element supply body, while airflow is prevented in the reaction space.
2. The catalyst according to claim 1 , wherein the casing is made of stainless steel.
3. The catalyst according to claim 1 , wherein the metal-element-supply body further comprises iron (Fe) as a metal element.
