Abstract
An electrochemical cell having a hydraulically impermeable permselective membrane is operated more efficiently by (1) separating the anode and the cathode of such a cell from the permselective membrane by a spacing means which is porous, hydrophilic, and electrically non-conductive, or alternatively, (2) providing a coating on the metal electrodes of said cell which is hydrophilic, porous, and electrically non-conductive. Said spacing means is of a material selected from the group consisting of at least one of mineral fibers, synthetic organic polymers, and ceramics and glasses.
