NOVELTY - A generating device for generating hydrogen gas, has a vessel holding an electrolyte solution, a membrane arranged to form a chamber, a cathode within the electrolyte solution; an anode in the vessel but not in the chamber, a hydrogen gas collection area, and a hydrogen gas exhaustion arrangement coupled to the collection area.    USE - For generating hydrogen gas, by generating an electric current; applying the electric current to the cathode and the anode, where the cathode and the anode are immersed in the electrolyte solution; conducting the protons through the membrane; generating the hydrogen gas at the cathode and the oxygen gas at the anode; using the membrane as the barrier between the hydrogen gas and the oxygen gas; and exhausting the hydrogen gas. (Claimed)    ADVANTAGE - The inventive device is efficient and scalable for generating hydrogen gas. It may be configured to generate hydrogen gas using only renewable sources of energy. Further, it is deployable in a contained vessel, and provides a simple membrane structure for keeping the hydrogen gas separated from the oxygen and from other contaminates. It is easily mass-produced and arranged in units, thus reducing the overall cost to the consumer. It eliminates the traditional electrolyzer used to make hydrogen with electricity, thus eliminating the 40% inefficiency in the operation of the electrolyzer. It is environmentally friendly, and may be used to generate hydrogen in a wide variety of locations.
