OXYGEN GAS DIFFUSION ELECTRODE

摘要

An improved flexible graphite fabric gas diffusion cathode for an electrolytic cell has a first hydrophobic cathode surface contacting electrolyte in the cell and a second cathode surface forming an upper surface of the cell. The improvement comprises a plurality of perforations in the flexible cathode to provide a series of vents, each perforation having sufficient open area that the force of gravity on the electrolyte is greater than the capillary forces of the perforation on the electrolyte. This prevents a localized nonuniform flow of electrolyte in the cell when the flexible electrode is disposed in a generally horizontal position with the first surface contacting the electrolyte and the second surface forming an upper surface of the cell.
