  • Patent number: 11479870
    Abstract: An electrolysis cell includes an anode chamber and a cathode chamber separated by an ion-exchange membrane. The electrolysis cell includes an anode, a gas diffusion electrode, and a cathode current distributor. The anode, the ion-exchange membrane, the gas diffusion electrode, and the cathode current distributor are in direct touching contact in the mentioned order. Flexibly resilient holding elements are arranged on the other side of the anode and/or on the other side of the cathode current distributor. The flexibly resilient holding elements exert a contact pressure on the anode and/or on the cathode current distributor. The flexibly resilient holding elements have annular elements, the axis of which is oriented in the height direction of the electrolysis cell. By means of the flexibly resilient and in part also plastically deforming annular elements, effective mechanical contact pressure of the ion-exchange membrane against the oxygen-depolarized cathode is achieved.

    Abstract: In the method and system, a number of electrolytic cells are arranged as a cell group, which cells are separated by a number of partition walls; in each cell, a number of anodes and cathodes are arranged in an alternating order, so that in each cell, next to each anode, there is arranged a cathode, and so that in each cell, each individual anode is fitted in the same anode line with the anode of the adjacent cell, and in each cell, each individual cathode is fitted in the same cathode line with the cathode of the adjacent cell, and each anode is galvanically connected to at least one cathode of the adjacent cell. The flowing direction of the current passing in the cell group is deviated in different directions in order to make the current flow mainly in the direction of the cell group.

  • Patent number: 8303798
    Abstract: The invention is a unit that produces Hydrogen Gas (Browns Gas (HHO)) that can be used as an assist to diesel and gas engines. The gas is produced from distilled water, using our stainless steel plate design. The patent should apply to the internal plate placement and design. The internal design of the unit allows it to produce significantly more hydrogen, drawing significantly less current or electricity from its power source. The internal design is in the placement of positive, negative and neutral plates to produce the gas.

  • Patent number: 8021526
    Abstract: A household appliance incorporating an electrolyzer for electrolysis of water to H2 and O2 and an electrolyzer therefor. The appliance may include a burner for the hydrogen produced and an electric conductive member to provide household current to the electrolyzer. The electrolyzer comprises an outer housing defining a chamber which houses at least one cathode and at least one anode. The electrolyzer may comprise a plurality of field electrodes and the field electrodes may comprise first and second field electrodes which are electrically connected together and spaced apart to define an intra cell gap. Field electrodes may then be spaced apart to define an inter cell gap between electrodes of adjacent field electrodes. At least one of the anode and cathode may be connected to an electrically conductive member that is molded in situ in the housing and at least some of the electrodes may be configured to dimensionally stabilize the electrodes during operation of the electrolyzer.

  • Patent number: 7897022
    Abstract: A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode endplates held apart from each other by a pair of supports such that the supports enclose opposing sides of the endplates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.
