Randall Carr, L E Geoffroy, Rodger H Flagg, Donald L Carr: Method and apparatus for producing hydrogen. November 11, 1980: US04233132 (17 worldwide citation)

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 reco ...
