NOVELTY - An electric cell comprises an oxidizing electrolyte in aqueous solution, containing a peroxide and a hypochlorite, such that the weight ratio of hypochlorite to peroxide in the electrolyte is not less than 5:1; an anode made of a Group IIIA metal or its alloy; and a cathode. The electrolyte is formed by adding the peroxide to the hypochlorite. The electric cell further comprises a chlorine-stabilizing compound.    USE - As an electric cell useful for producing hydrogen gas to generate electricity; useful in battery, fuel cell (claimed), capacitor and hybrid battery/fuel cell system; useful as a galvanic or electrochemical cell; useful in energy production and storage devices; useful in hydrogen-powered devices such as internal combustion engines, heating systems and fuel cells; and useful in hydrogenation performed in chemical processes, jet propulsion and rocket fuel.    ADVANTAGE - The electric cell generates electricity and hydrogen on demand, by using the combination of peroxide, alkali hypochlorite and metal anode. The cell produces hydrogen only on demand when needed, thus eliminating the need to store hydrogen under high pressure in a gas tank. Thus, the electric cell provides hydrogen gas without the hazards associated with storage and transport of liquid hydrogen gas. The byproducts (e.g. sodium chloride, aluminum hydroxide and trace of permanganate ion) produced by the electric cell during hydrogen generation process, are environmentally benign and recyclable. The electrolyte solution of the cell can be used in deicing frozen highways, reducing the amount of salting that is required for safe, ice-free motoring. Refueling of hydrogen-powered device with the electric/galvanic cell involves changing the metal anode (e.g. aluminum-manganese anode) and providing a fresh tank of the oxidant electrolyte, where both the metal anode and oxidant electrolyte are stable and safe. The electric cell produces a significant current density (e.g. 23 mA/cm2) at a useful voltage (e.g. 1.6-1.7 Volts per cell); and produces hydrogen gas with a maximum production, which is close to the theoretical maximum of 1.5 moles of hydrogen per mole of expended anode material. The chlorine-stabilizing compound increases the hydrogen-production efficiency of the cell.
