NOVELTY - Compact hybrid cell hydrogen generator comprises a sealed housing containing the solution, where gases produced exit the housing via inlet and outlet apertures; electrolyte solution; a water supply unit adapted to maintain the electrolyte; regularly spaced metallic plates; and fluid flow passageway. At least some of the fluid entering the fluid flow passageway and exiting through the outlet flows through at least one section of the fluid flow passageway.    USE - Compact hybrid cell hydrogen generator for producing hydrogen-oxygen gas for use with internal combustion engines.    ADVANTAGE - A reliable, compact, and cost efficient system of producing hydrogen-oxygen gas is provided without requirements or investments into expensive infrastructure or cumbersome equipment.    DETAILED DESCRIPTION - Compact hybrid cell hydrogen generator comprises a sealed housing containing the solution, where gases produced exit the housing via inlet and outlet apertures; electrolyte solution partially filling an electrolysis chamber and gathering in a gas accumulation chamber above the chamber; a water supply unit adapted to maintain the electrolyte; regularly spaced metallic plates; and fluid flow passageway. Each of the apertures are within the periphery of the housing being positioned such that at least some of the fluid entering the fluid flow passageway through the inlet and exiting through the outlet flows through at least one section of the fluid flow passageway. At least one anode and one cathode are provided with an entrance channel and an exit channel, positioned such that application of an electrical potential across such electrodes causes field lines to pass through the at least one section of the electrolytic process chamber comprising at least one metallic plate. The apparatus includes a collection unit for gases produced by the electrolysis. The collection unit comprises a method for purifying and filtering the gases; a unit to introduce the gases into air intake of internal combustion engine; and a method for preventing flashback of the gases.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view showing the compact hydrogen generator.
