Abstract:
An electrolytic cell employing an anode, an ion-exchange membrane and an oxygen cathode comprising a gas diffusion electrode, characterized in that a caustic chamber frame comprising an upper chamber, as caustic solution discharge openings, and a lower chamber, as caustic solution introduction openings, which are connected to each other through caustic solution passageways is disposed at outer edges of the electrolytic cell which comprises: a gas chamber having oxygen gas outlets and inlets for the gas diffusion electrode which meet upper- and lower-chamber oxygen gas outlets and inlets formed on the center side of and adjacently to a cathode element along the plane of a cathode collector frame; and a cathode chamber which is the space between the gas diffusion electrode and the ion-exchange membrane and into which a caustic solution is to be introduced.
