NOVELTY - Reactor for production of hydrogen and zinc oxide and electric power, comprises a container, within which there are provided a cell and a solution. The cell provides at least two first zinc elements or plates and at least two second metallic elements or plates. The first and second plates are connected by short-circuit or on external load. The solution comprises at least water (H2O), CnH2nOn (n=3-7) and sodium hydroxide (NaOH) or potassium hydroxide (KOH).    USE - The reactor or method is useful for production of hydrogen and zinc oxide and electric power (claimed).    ADVANTAGE - System containing metallic plates is provided for the hydrogen production with high yield, starting from a solution of electrolytes and glucids, suitable to develop large hydrogen amount from the transformation of metals, transforming the same in oxides suitable for some industrial and energetic fields.    DETAILED DESCRIPTION - Reactor for production of hydrogen and zinc oxide and electric power, comprises a container, within which there are provided a cell and a solution. The cell provides at least two first zinc elements or plates and at least two second metallic elements or plates. The first and second plates are connected by short-circuit or on external load. The solution comprises at least water (H2O), CnH2nOn (n=3-7) and sodium hydroxide (NaOH) or potassium hydroxide (KOH), the H2O, CnH2nOn (n=3-7) and NaOH or KOH being present in the solution, respectively, according to the following weigh ratios: H2O at 1000 g CnH2nOn (n=3-7) at 10-700 g; and NaOH or KOH at 10-700 g. The cell is immersed within the solution. An INDEPENDENT CLAIM is included for a method for production of hydrogen and zinc oxide, which involves insertion in a container of at least two first zinc elements or plates, and at least two second metallic elements or plates; insertion in the container of the solution; extraction of obtained hydrogen and sine oxide and possibly withdrawal of the electric power produced by the chemical, reaction.
