NOVELTY - The electrolyzer has a conductive sleeve (203) that is disposed within the non-conductive grommets (204) at the corresponding apertures of a positive conductive busbar (206) and a negative conductive busbar (205). The sleeve has an aperture through which one of the conductive busbars passes and makes an electrical connection with the conductive sleeve. The sleeve creates an electrical connection between two negative electrode plates (201) or between two positive electrode plates (202).    USE - Electrolyzer for dissociating water into hydrogen and oxygen.    ADVANTAGE - The placement of the apertures, and the resulting electrical connections to the conductive busbars, minimize the distance that current travels to/from any point on the surface of the electrode plate. While it is undesirable to waste electrical energy in heating the electrolyte solution, the introduction of water vapor into an air fuel mixture, e.g., of an internal combustion engine, reduces air pollution, increases engine efficiency/reduces fuel consumption, reduces combustion temperature of the engine, and reduces accumulation of carbon deposits in the engine. The perforations generate currents of electrolyte fluid away from the surfaces of electrode plate during electrolysis, increasing circulation of the electrolyte solution, sweeping away bubbles that form on the electrode plates, promoting ionic migration, and equalizing the ion concentration between anodes and cathodes. The location of apertures, in opposite corners of electrode plate, promotes an even current density distribution across electrode plate by minimizing the distance the electric current flows between the portions of electrode plate that make a physical and electrical connection with respective conductive busbars passing through apertures and the other portions of electrode plate.    DETAILED DESCRIPTION - The positive conductive busbar extends through the first aperture (102) of each positive electrode plate (202) and through the non-conductive grommet of the second aperture (111) of each negative electrode plate (201). The negative conductive busbar extends through the first aperture of each negative electrode plate and through the non-conductive grommet of the second aperture of each positive electrode plate.
