PURPOSE:To reduce the necessary power during operation and to improve the total energy efficiency of a cell by storing or feeding an active material or halogen in a cell while dissolving into hexachlorobutadien. CONSTITUTION:A cell employing halogen as an active material such as a zinc/ chlorine cell is assembled with a cell section 2 employing chlorine as a positive electrode active material while zinc as a negative electrode active material, an electrolyte section 3, a chlorine gas storing tank 1, a cooling/heating section 6 and a liquid circulation system and gas circulation system 4, 5. Zinc chloride aqueous solution and hexachlorobutadien are contained respectively in the electrolyte section 3 and the chlorine gas storing tank 1. By utilizing the fact that the solubility of halogen against hexachlorobutadien will vary with the temperature, the temperature is lowered at the time of absorbing halogen while raised at the time of producing, thus performing charge/discharge. Consequently, halogen can be stored as an uniform solution with simple facility, resulting in improvement of the efficiency. |
