NOVELTY - An electrolytic cell (2) includes a separator (10) having a first inclined surface to direct flow of the electrolyte and the first gas due to a difference between density of the electrolyte and combined density of the electrolyte and the first gas. The separator further includes a second inclined surface to direct flow of the electrolyte and the second gas due to a difference between density of the electrolyte and combined density of the electrolyte and the second gas.    USE - Electrolytic cell for producing hydrogen and oxygen.    ADVANTAGE - The electrolytic cell can tolerate impurities and products of operation.    DETAILED DESCRIPTION - An electrolytic cell (2) comprises a containment vessel for pressurization; two electrodes; a source of electrical current; an electrolyte; a first gas which is formed during electrolysis at or near the first electrode; a second gas which is formed during electrolysis at or near the second electrode; a separator (10); and two gas collection vessels. The separator includes a first inclined surface to direct flow of the electrolyte and the first gas due to a difference between density of the electrolyte and combined density of the electrolyte and the first gas such that the gas flows in a direction distal the second electrode and towards the first gas collection vessel. The separator includes a second inclined surface to direct flow of the electrolyte and the second gas due to a difference between density of the electrolyte and combined density of the electrolyte and the second gas such that the gas flows in a direction distal the first electrode and towards the second gas collection vessel. An INDEPENDENT CLAIM is included for a method of improving the efficiency of an electrolytic cell comprising:    (A) providing an electrolytic cell;    (B) performing electrolysis in the electrolytic cell where a first gas and a second gas is produced in the electrolytic cell during the electrolysis;    (C) providing a first gas collection vessel distinct from the electrolytic cell and in fluid communication with the electrolytic cell;    (D) capturing the first gas in the first gas collection vessel prior to substantial expansion of the first gas;    (E) expanding the first gas;    (F) capturing work generated from the expansion of the first gas;    (G) providing a second gas collection vessel distinct from the electrolytic cell and in fluid communication with the electrolytic cell;    (H) capturing the second gas in the second gas collection vessel prior to substantial expansion of the second gas;    (I) expanding the second gas; and    (J) capturing work generated from the expansion of the second gas.
