Abstract
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
