ION-EXCHANGE MEMBRANE ELECTROLYTIC CELL EQUIPPED WITH GAS DIFFUSION ELECTRODE |
摘要 |
PROBLEM TO BE SOLVED: To provide an ion-exchange membrane electrolytic cell equipped with a gas diffusion electrode which is operated with a low voltage and a high current efficiency. SOLUTION: In the ion-exchange membrane electrolytic cell 1 equipped with the gas diffusion electrode, a frame-shaped cathode gasket 6 is placed in contact with an ion-exchange membrane 3. Catholyte-distribution means 10a and 10b, which are thinner than the frame-shaped cathode gasket 6, are located in a cathode chamber 7 formed by the frame-shaped cathode gasket 6, the ion-exchange membrane 3 and the gas diffusion electrode 20. The catholyte-distribution means 10a and 10b each has apertures on the surface opposite the ion-exchange membrane 3 and on the surface near the center of the cathode chamber, which communicate with each other. The apertures formed on the surface opposite the ion-exchange membrane 3 also communicate with an upper or lower catholyte chamber 11a or 11b. COPYRIGHT: (C)2005,JPO&NCIPI
