NOVELTY - Electrolytic cell (2), comprises: a containment vessel (4); a first electrode; a second electrode; a microorganism to promote electrolysis, where the microorganism is retained on the surface of at least one of the first electrode or the second electrode; a source of electrical current in electrical communication with the first electrode and the second electrode; an electrolyte in fluid communication with the first electrode and the second electrode; a gas, where the gas is formed during electrolysis at or near the first electrode; a gas extraction area; and a separator (10).    USE - The electrolytic cell is useful for producing hydrogen (which are used to produce carbon free liquid fuels including ammonia and designer fertilizers, or for mixed distribution in natural gas infrastructure e.g. pipelines and wells) and oxygen.    ADVANTAGE - The electrolytic cell: reversibly separates the production of pressurized hydrogen and oxygen; tolerates impurities and products of operation; exhibits greater electrical efficiency, more rapid dissociation, and greater separation efficiency along with prevention of undesirable side reactions, thus increasing the rate and efficiency of ion production and delivery to electrodes and increasing the system efficiency and current limit per electrode area; can operate efficiently in severe cold or hot conditions without regard for various proton exchange membrane related difficulties, limitations, and failures; and exhibits tolerance to high current conditions, thus achieving high electrolysis efficiency without the problems of proton exchange membrane degradation or electrode-interface failures.    DETAILED DESCRIPTION - Electrolytic cell (2) comprises: a containment vessel (4); a first electrode; a second electrode; a microorganism to promote electrolysis, where the microorganism is retained on the surface of at least one of the first electrode or the second electrode; a source of electrical current in electrical communication with the first electrode and the second electrode; an electrolyte in fluid communication with the first electrode and the second electrode; a gas, where the gas is formed during electrolysis at or near the first electrode; a gas extraction area; and a separator (10), where the separator comprises a substantially continuous helical configuration having two inclined surfaces forming a V shape, where 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 and the gas so that the gas substantially flows in a direction distal to the second electrode, and the separator is further 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 electrode and the second electrode.
