  • Method and apparatus for producing hydrogen
    Patent number: 4233132
    Abstract: Electrodes are immersed within oil which forms a layer over a quantity of water. When current is passed between the electrodes which are held to a predetermined gap from the interstitial surface between the oil and water, water is caused to undergo electrodecomposition. Gaseous hydrogen is then recovered in the sealed space above the oil-water layers and the oxygen is caused to react with constituents in the oil layer.Consequently, there is produced continuously a quantity of hydrogen which is separately collected and is usable in gaseous form.
