Abstract: The present disclosure relates to a water electrolysis apparatus including a diaphragm for removing a dissolved gas from an electrolyte. By separating a dissolved gas present in an electrolyte through a diaphragm provided in a gas-liquid separator or an electrolyte circulation line, the water electrolysis apparatus can increase the efficiency of production of the dissolved gas in the electrolyte while preventing a gas composition from reaching an explosive limit in a gas phase region of the water electrolysis apparatus.

Abstract: Disclosed is an electrolysis device including an electrolytic cell composed of an anode compartment equipped with an anode, a cathode compartment equipped with a cathode, and a diaphragm separating the anode compartment and the cathode compartment from each other. The device further includes an alkaline solution supply unit for supplying an alkaline solution as an electrolyte to the anode compartment, an acidic solution supply unit for supplying an acidic solution as an electrolyte to the cathode compartment, and first and second outlets for discharging electrolyzed water from the anode compartment and the cathode compartment, respectively. In the anode compartment, hydroxide ions of the alkaline solution generate oxygen through an electrode reaction, and, in the cathode compartment, hydrogen ions generate hydrogen through an electrode reaction.
