A DEVICE USING ELECTROLYZER WITH A BIPOLAR MEMBRANE AND THE METHOD OF PRODUCING HYPOCHLORITE SOLUTION AND HYDROGEN GAS THEREBY

摘要

The purpose of the present invention is to provide a seawater electrolysis device using a bipolar membrane and a method for producing hypochlorite and hydrogen using the same. For the purpose, the present invention provides a seawater electrolysis device using a bipolar membrane, comprising an electrolysis reaction part which is separated into an anode part and a cathode part by a bipolar membrane in the middle, wherein the anode part includes an anode to generate a hypochlorite solution and oxygen gas by receiving and electrolyzing seawater, and the cathode part includes a cathode to generate hydrogen gas by receiving and electrolyzing seawater; and a first gas-liquid separator for receiving the hydrogen gas generated by the cathode part of the electrolysis reaction part and the seawater and separating the hydrogen gas and the seawater. Also, the present invention provides a method for producing hypochlorite and hydrogen via seawater electrolysis using the device. According to the present invention, the reproduction of ocean life can be prevented in a seawater inflow pipe for cooling a power plant condenser by producing a hypochlorite solution and high-purity hydrogen and oxygen simultaneously from seawater. And additional electricity can be produced using the generated hydrogen and oxygen.
