NOVELTY - The electrolytic cell (2) comprises a containment vessel, a first electrode (4), a second electrode (8), a source of electrical current in electrical communication with the first and second electrodes, an electrolyte in fluid communication with the first and second electrodes, a gas formed at or near the first electrode during electrolysis, a gas extraction area, and a separator (10) comprising a continuous multiple start helical configuration having two inclined surfaces forming a V shape. The separator directs flow of the electrolyte and the gas.    USE - The electrolytic cell is useful for production of gases including pressurized hydrogen and oxygen.    ADVANTAGE - The electrolytic cell efficiently, rapidly and economically produces the gas with improved operation speed, less number of equipments, less energy consumption and increased rate of hydrogen production and without any impurities and proton exchange membrane degradation or electrode-interface failures.    DETAILED DESCRIPTION - The electrolytic cell (2) comprises a containment vessel, a first electrode (4), a second electrode (8), a source of electrical current in electrical communication with the first and second electrodes, an electrolyte in fluid communication with the first and second electrodes, a gas formed at or near the first electrode during electrolysis, a gas extraction area, and a separator (10) comprising a continuous multiple start helical configuration having two inclined surfaces forming a V shape. The separator directs flow of the electrolyte and the gas due to a difference between density of the electrolyte and the combined density of the electrolyte such that the gas flows in a direction distal to the second electrode, and is configured to promote circulation of the electrolyte between the first electrode, the gas extraction area, and the second electrode to provide fresh electrolyte to the first and second electrodes. The separator comprises the first electrode, and a dielectric material. The electrolytic cell further comprises a microorganism. The separator retains the microorganism in a desired location. The first and second electrodes are configured to allow the polarity of the first and second electrodes to reverse. The first electrode comprises a first conductive material proximal to the source of electrical current, a dielectric material distal to the source of electrical current, a second conductive material proximal to the dielectric material and distal to the source of electrical current, and a spring structure for vibration to promote release of nucleated gas from the electrodes. The first electrode is configured to vibrate at a rate to promote circulation of the electrolyte.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of an electrolytic cell.
