NOVELTY - An electrode for use in a hydrolysis cell (12), comprises a series of non-vertically oriented perforated electrically conducting wafers (32, 33), vertically spaced from each other in a congruent stack, and a connector for connecting each wafer of the series to an electrical circuit.    USE - The electrode is used in hydrolysis cell useful for generating hydrogen and oxygen from water (claimed) for delivery to internal combustion engines.    ADVANTAGE - The electrode reduces noxious emissions to the environment, reduces engine maintenance and reduces fuel costs.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a hydrolysis cell for generating hydrogen and oxygen from water, comprising a casing comprising upper and lower chambers sealed together, and where the lower part is electrically conductive and comprises a cathode; mechanism for introducing make-up liquid into the cell; mechanism for removing produced gas from the cell, where the upper and lower chambers being separated by a gas and liquid impervious divider which forms a seal between the upper and lower parts, the divider having at least one opening permitting passage of gas from the lower part to the upper part and a gas-porous but substantially liquid impervious filter retained within the opening to inhibit passage of liquid while permitting passage of gas; and    (2) a hydrolysis system comprising an electrolytic cell for hydrolysis of water, a water reservoir independent of the cell, a vacuum pump for evacuating the cell to draw water into the cell from the reservoir when required for replenishing, a gas conduit (17) leading from the cell for discharge of gases during operation of the cell, a power source, and a control subsystem for detecting a low liquid level and actuating the vacuum pump in response, a ball valve for controlling the flow of water into the cell and gas out of the cell comprising first, second, third and fourth ports, a ball for controlling flow through the ports and a ball valve actuator for rotating the ball to selectively block flow through the ports, a first conduit for conducting liquid from the reservoir to the first port, a second conduit for conducting liquid from the second port to the cell, a third conduit for conducting gas from the chamber to the third port; a fourth conduit for conducting gas from the fourth port to the vacuum pump, the valve actuation unit is for rotating the ball between a first position the ball valve blocks passage through all of the ports to block the inflow of liquid into the cell while blocking the outflow flow of gas through the third conduit, and a second position where all of the ports are open for replenishment of the cell.
