A cell arrangement for the electrolysis of water to liberate hydrogen and oxygen gases is described. A cell unit (125) has a stacked arrangement of segmentation disks (114), a first type of (anode) cell plates (90), a second type of (cathode) cell plates (98) and separation membranes (116). Interconnecting conductive shafts (126-131) pass through holes (100, 102) of the cell plates (90,98) to have selective electrical interconnection therewith. Water and electrolyte are supplied by inlet ports (108, 110) to immerse the cell plates (90, 98). The membranes (116) normally isolate adjacent cathode and anode plates (90, 98) from the mixing of liberated oxygen and hydrogen gases while allowing ionic current to flow. By selective adjustment of the water/electrolyte pressure differential on the respective sides of the separation membranes (116), the admixture of the liberated gases can be produced. The liberated gases discharge through outlet ports (104,106).

[ I claim:] [1.] A cell arrangement for the electrolysis of water, the arrangement comprising:a plurality of anode-forming electrodes in a parallel stacked relation, each anode electrode comprising a flat plate, and through which plates one or more conductive first interconnecting members pass and are electrically connected thereto; anda plurality of cathode-forming electrodes in a parallel stacked relation, each cathode electrode comprising a flat plate, and through which plates one or more conductive second interconnecting members pass and are electrically connected thereto;and wherein the anode electrodes and the cathode electrodes are interleaved, and the first interconnecting members and the second interconnecting members also pass through without electrical connection to apertures in the cathode electrodes and the anode electrodes, respectively. [12.] An electrolysis system comprising:a cell arrangement as claimed in claim 1, and further comprising:a tank adapted for containing and immersing said cell arrangement in at least water, andDC voltage supply means, the positive supply of which is coupled to the anode electrodes and the negative supply of which is coupled to the cathode electrodes by a respective ones of the first and second interconnecting members to liberate oxygen and hydrogen gases respectively from said anode electrodes and said cathode electrodes. The electrolysis system as claimed in claim 12, further comprising:pipe means to collect said hydrogen and oxygen gases as a gas admixture, andgas scrubbing means through which the collected gas passes, said gas scrubbing means having at least two separate passageways through which the admixed gas is forced to pass separated by at least one scrubbing liquid. The electrolysis system as claimed in claim 13, wherein said scrubbing means comprises:a tank adapted for containing the scrubbing liquid to a partial level of the tank, andat least two vertically arranged columns within the tank,the first column having an upper end thereof for receiving the collected admixed gas and a lower end thereof open to the scrubbing liquid, andthe second column having an upper end thereof open to receive firstly scrubbed gas and a lower end thereof open to the scrubbing liquid, the secondly scrubbed gas passing to outlet port means. The electrolysis system as claimed in either one of claims 13 or 14, further comprising flow restrictor means through which said collected gas passes, thereby creating a back pressure on water in the tank. [16.] The electrolysis system as claimed in claim 12, further comprising:a plurality of membranes, each of said membranes located between an adjacent anode electrode and cathode electrode, said membranes allowing the passage of ionic current between adjacent electrodes, but selectively blocking the flow of gas therethrough dependent upon a controllable pressure differential across the membrane. The electrolysis system as claimed in claim 16, further comprising:a first water supply, said first water supply for providing water to the spaces surrounding the anode electrodes, anda second water supply, said second water supply for providing water to the spaces surrounding the cathode electrodes,adjacent anode and cathode spaces being separated by a said membrane, andwherein one of the said water supplies can be selectively pressurized by a pressurization unit so that a pressure differential exists across each membrane, thus permitting the flow of gas liberated by the anode or cathode electrode during electrolysis through the membrane. The electrolysis system as claimed in claim 17, wherein said pressurization unit which pressurizes the one water supply includes a pump means. The electrolysis system as claimed in claim 18, wherein each said water supply has an inlet and an outlet in communication with a tank adapted for enveloping the anode electrodes and cathode electrodes, and wherein said pump means is located within the inlet for either the anode electrodes or the cathode electrodes.
