An improved electrolysis system is disclosed in which the tank is designed to operate with a plurality of electrodes that are connected in a parallel plate configuration to a DC power source. The electrode geometry provides a means in which the height of the electrodes is lessened by increasing the length of the electrodes to provide the necessary area for any given current input. The lessened height of the electrode reduces the travel path of the gases escaping to the surface thereby reducing the void fracture height area of the bubbles and increasing the overall system efficiency. Additional efficiencies are obtained with a high surface area of contact between the electrical bus segments and the electrodes.
