Abstract
There are provided an electrolyzer gasket, which can accommodate and hold a separator inside an electrolyzer by a simple handling, can more surely prevent leakage of an electrolyte and an electrolytically generated gas from the inside of the electrolyzer, can keep the separator in such a state that the separator is held at a position that is in contact with one of electrodes and is located along the electrode and therefore can suppress damage of the separator and makes it possible to use the separator stably for a long period of time, and an electrolyzer. An electrolyzer gasket including a picture-frame-shaped thin-plate-like frame having a first surface being in contact with an anode metal frame and a second surface being in contact with a cathode metal frame, wherein the gasket has a structure in which a notch having a difference in level of approximately the same thickness as the thickness of the separator, the notch obtained by thinly scraping off, in a uniform thickness, a region including the edge on the anode chamber side or the cathode chamber side, is formed on any one of the first surface and the second surface, and the edge part of the separator is accommodated and held in the notch, and an electrolyzer using the electrolyzer gasket.
