Abstract
An apparatus for producing hydrogen and oxygen having a pressure vessel surrounding a bipolar-type water electrolytic cell The electrolytic cell contains a plurality of joined solid electrolyte membrane units, and each solid electrolyte membrane unit contains a solid electrolyte membrane, porous conductors in contact with opposing surfaces of the solid electrolyte membrane, and bipolar-type electrode plates in contact with each porous conductor, wherein each electrode plate is capable of performing as an anode and a cathode. A gap is present between the interior of the pressure vessel and the exterior of the water electrolytic cell to form a water pressure regulating chamber, and water of a preselected pressure can be fed into the water pressure regulating chamber such that the pressure differential between the pressure inside the water electrolytic cell and the pressure inside the water pressure regulating chamber is maintained within the pressure differential tolerance range of the water electrolytic cell.
