Provided is an alkaline water electrolyzer in which leakage of aqueous alkali solutions is prevented. The alkaline water electrolyzerincludes an anode chamber framedefining an anode chamber; a cathode chamber framedefining a cathode chamber; a porous diaphragmdisposed between the anode and cathode chamber framesandand partitioning the anode and cathode chambersand; an anode gasketdisposed on the anode chamber frame; and a cathode gasketdisposed on the cathode chamber frame, wherein when the anode and cathode chamber framesandare fastened, the porous diaphragmis held between the anode and cathode chamber framesandvia the anode and cathode gasketsandand the anode and cathode gasketsandare in contact with each other around the peripheral edge of the porous diaphragmby compressing the anode and cathode gasketsand

Alkaline water electrolysis device

An electrolytic cell that prevents, or at least minimizes, damage to a membrane and reduces electrolytic voltage may include an elastic member attached to an electrolytic partition wall within an anode chamber and/or a cathode chamber. The elastic member comprises a spring retaining part and a bonding part that is bonded to the electrolytic partition wall, parallel first support parts extending from the bonding part away from the electrolytic partition wall, a second support part connecting the first support parts, and two parallel spring rows. Each spring row may include first flat spring-like bodies, which originate from the first support part and extend toward the opposite direction of the electrolytic partition wall, and second flat spring-like bodies, which originate from the second support part and extend toward the opposite direction of the electrolytic partition wall.
