Abstract

An electrolytic cell has dimensionally stable anodes 4, non- porous ion-selective membranes 8 separating the anodes from a cathode compartment in a cathode container 1 and a porous, static bed of loose, particulate conducting cathodic material 10 in the cathode compartment of the container. The cathodic material extends between conductive walls of the cathode compartment and the membranes and contacts the conductive walls of the cathode and the membranes to carry current between the walls of the cathode compartment and the membranes. This construction reduces the electrodic gap to substantially the thickness of the membranes and presses the membranes against the anodes. It produces greater uniformity of current density over the entire electrodic area, substantially free from localised differences of current density which tend to cause deterioration of the membranes by the creation of localised mechanical and electrical stresses in other types of cells. The invention also provides a method for carrying current from the effective cathodic surface to the walls of the cathode compartment.
