NOVELTY - Water is pressurized and water fog is spouted to decomposition chamber (16). Water molecules are ionized to generate hydrogen and hydroxyl ions. Hydrogen ions are captured by hydrogen-capturing electrode (7) to react as hydrogen, and hydroxyl ions are captured by oxygen-capturing electrode (9) to react as oxygen and hydrogen. Hydrogen is output and used as fuel or purified to be used as chemical raw material. Oxygen and unreacted water fog are decomposed to obtain by-product oxygen. The decomposed water and residual water are returned for recycle.    USE - Production of hydrogen. The hydrogen-production equipment can be used as gas-agent generator for gasification equipment, and as oxygen generator.    ADVANTAGE - The method reduces consumption of electric energy, speeds-up reaction, and does not use fossil energy.    DETAILED DESCRIPTION - Water is pressurized through a water pump, and water fog is spouted to a spraying decomposition chamber in an electrical machine integrated hydrogen-production device through an atomization nozzle (19). Water molecules are ionized by mechanical force and electric-field force to generate hydrogen and hydroxyl ions. Hydrogen ions are captured by hydrogen-capturing electrode to react as hydrogen, and hydroxyl ions are captured by oxygen-capturing electrode to react as oxygen and hydrogen. Hydrogen is output from the outlet at the device top and used as fuel or purified to be used as chemical raw material. Oxygen and unreacted water fog are output from the lower portion of the device and decomposed to obtain by-product oxygen. The decomposed water is returned to water tank for recycle, and the residual water is output from the device bottom and returned to the water tank for recycle. Also claimed is, hydrogen-production equipment.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the hydrogen-production equipment.
