PURPOSE:To improve performance at a low cost by separating a positive electrode chamber and a negative electrode chamber with a cation exchange membrane, forming the positive electrode chamber with a carbon plate as a basic constituting body, filling it with concentrated nitric acid, filling the negative electrode chamber with an electrolyte, and inserting a zinc plate. CONSTITUTION:A basic constituting body is formed with a cation exchange membrane 1 and a positive electrode carbon plate 4 installed in a positive electrode chamber 2 and a negative electrode chamber 3 separated by the membrane 1. The positive electrode chamber 2 is filled with concentrated nitric acid serving as an oxidizer, and the negative electrode chamber 3 is inserted with a zinc plate 5 and filled with an electrolyte 7. Electrons are discharged by the electrolyte 7 from metal zinc to a zinc electrode 25 and converted into zinc ions in the negative electrode chamber 3. A concentrated nitric acid aqueous solution is dissociated into hydrogen ions and nitric acid ions in the positive electrode chamber 2, hydrogen ions receive electrons from a carbon electrode 24 to be converted into hydrogen molecules, and hydrogen molecules are oxidized by concentrated nitric acid and converted into water and nitrous acid. Zinc ions transmit the exchange membrane 1 to form zinc nitrate. The power generation heating reaction at the ordinary temperature and ordinary pressure is reduced, and good performance is obtained at low cost. |
