(WO9300459-A1)      Efficient operation of electrolysis cells with at least one separator and at least one capillary gap electrode. The electrolyte and the reaction gas which is produced or consumed in the electrolytic process, are conveyed separately, so that the electrolyte does not impede the transport of the reaction gas and the latter does not impair the electrolytic reaction. Cell comprises at least one separator, pref. in the form of a diaphragm or membrane, and at least one capillary gap electrode immediately adjacent to the separator. In partic., the cell consists of a number of electrode elements arranged parallel to each other, where the distance between them is such that a capillary effect is produced. Separate lines are used for the electrolyte and the reaction gas.    Pref. the electrolyte is contained in a sealed electrolyte space, and fed through the walls of this to the electrodes. The electrolyte of the capillary gap electrode is fed along the separator surface in the form of a falling film. The electrode elements are hydrophilic in the narrow electrolytically active region of the capillary gap electrode adjacent to the separator, and are hydrophobic in the remaining region remote from the separator.    USE/ADVANTAGE -   Used in water and chloralkali electrolysis cells, and in fuel cells. The ohmic resistance is reduced, and mass transfer is improved. Mfr. of the cell is simplified, and large active surfaces can be used.

(DE4120679-C2)      In an electrolysis process for gas-generating or gas-consuming electrolytic processes, partic. for chlor-alkali or water electrolysis and also for fuel cells, the cell contains a separator (1) with electrodes (2, 3) contacting it on both sides. A falling film passes through a hydrophilic region (10) of the uninterrupted capillary structure of the cathode, while gas passes through a hydrophobic region (11) into the capillary gaps of the reactive hydrophilic region. The anode is constructed in the same way. The hydrophobic region is free from electrolyte, which is fed into a sealed-off electrolyte chamber (21) and is supplied to the electrodes through the chamber walls.    ADVANTAGE -   Reduction of ohmic resistance and improvement of mass transport.
