NOVELTY - The device (1) has a membrane (17) separating a vessel (2) into a hydrogen chamber (3) provided with a cathode (9), and an oxygen chamber (4) provided with an anode (8). Electrolyte solutions (5) e.g. polymeric electrolyte, are placed in the hydrogen and oxygen chambers. Viologen additive i.e. herbicide, is placed in the electrolyte solutions. A hydrogen gas collection area is provided in the hydrogen chamber. A hydrogen gas exhaustion arrangement is coupled to the hydrogen gas collection area. A photovoltaic cell (19) is coupled to the cathode and the anode.    USE - Device for generating hydrogen gas used in fuel cells for electrical generation for residential use or for automobile and lorry energy using an electrolysis process and a renewable energy source e.g. renewable electricity source such as specially prepared/triple-junction silicon photovoltaic cell or panel. Can also be used for using a wind turbine, hydro turbine, commercial power grid or generator and a solar array.    ADVANTAGE - The device uses electro catalysts as an electrode or coating on the electrode to reduce an amount of energy needed to break apart and oxidize hydrogen gas. The device is scalable and easily mass produced and arranged in multiple units, thus reducing cost to a consumer and to produce hydrogen. The photovoltaic cell has 34 percent efficiency so as to accept higher concentrations of up to 400 suns, thus reducing output cost of the device. The device allows silicon cells provided with chemical resistant clear coating to protect the silicon cells from degradation, so that coating enhances electrical generation by concentration of solar energy. The device has a thinner profiled case about 25.4 mm thick or less by 741.2 mm by 1366.1 mm so as to reduce an amount of electrolyte and weight of a completed case for easier handling and suspension. The device employs cooling-heating transfer chips inside an electrolyte chamber to introduce mixing and stirring effect in electrolyte chemicals, so that stirring increases efficiency of water splitting reaction into hydrogen and oxygen, thus allowing electrical reactants to effectively arrive at a reaction site of water elements, and hence enhancing electro chemical reaction and producing hydrogen than without stirring. The device allows an inner coating to include polymer material for preventing hydrogen dispersion through a wall of a storage unit.
