Electrolytic cell using gas diffusion electrode and power distribution method for the electrolytic cell |
摘要 |
An electrolytic cell using an oxygen cathode, for use in an ion-exchange membrane electrolytic soda process or the like, the electrolytic cell having; a structure, wherein, for effective supply and discharge of a caustic liquid and for an effective handling of a caustic liquid leakage, provided on an outer-side edge of the electrolytic cell are an upper chamber as a caustic liquid discharge outlet, a lower chamber as a caustic liquid introduction inlet, and a caustic-liquid room frame connected via a caustic liquid passage to thereby reduce a caustic liquid leakage; a structure, wherein a lower gas chamber is provided at the lower outer end of a cathode element to thereby handle a caustic liquid leakage from a gas diffusion electrode to a gas room; or a structure which uses a gas-liquid permeating gas diffusion electrode to supply an oxygen gas from an upper chamber communicating with a gas room and discharge a gas and a caustic liquid into a lower chamber.
