Abstract
A process and cell for electrolysis of alkali metal halides, especially sodium chloride, are described, wherein the anolyte and catholyte compartments are separated by a fluorinated ion-exchange membrane whose surface facing the catholyte compartment is of a polymer having carboxylic functionality and which has a roughness which does not exceed 1.5 microns. Such a cell and process operate at high current efficiency, low voltage and low power consumption.
