ABSTRACT:
An electrolytic cell for producing sodium hydroxide, etc., which is partitioned by an ion-exchange membrane into an anode chamber and a cathode chamber, wherein at least one of a anode and a cathode is closely contacted to the ion-exchange membrane to form a gas diffusion electrode, and a current supplying means having guides for removing sodium hydroxide, etc., formed at the surface of the gas diffusion electrode is disposed therein closely contacting the gas diffusion electrode.
By having a current supplying means having removing guides, sodium hydroxide formed at the surface of the gas diffusion electrode is separated therefrom and removed, whereby the supply of the raw material gas and removal of the produced gas can be smoothly performed without clogging perforations of the gas diffusion electrode with the sodium hydroxide.
