(WO9222681-A1)      An electrolysis cell, for gas evolving or consuming electrolytic processes, has one or more electrodes with a quasi one- or two-dimensional capillary structure at the reaction-side edge region such that gas and electrolyte transport proceeds transversely to the electrode plane. The novelty is that one or more capillary gaps are connected to the edge region and oppose gas and electrolyte transport along the electrode plane, esp. in the vertical direction, with less resistance than the edge region.    In the operation of the cell, the novelty is that (a) during the cell start-up phase, the electrolyte level is sufficiently high that gas bubble evolution causes electrolyte transport to the upper electrode edge so that the electrode is fully supplied with electrolyte, this being dependent on cell geometry, material properties, pressures, temp., voltage and current; and (b) on transition to the operative state, the electrolyte level is opt. lowered at most by an amount still ensuring uninterrupted supply of the entire electrode.    USE/ADVANTAGE -   The cell is used e.g. for water-electrolysis. It has improved electrolyte and gas transport properties, increased efficiency and, because of its compactness, a good space-yield ratio. The cell operation is reliable and efficient and avoids aerosol formation so that a dry gas prod. is obtd..    (DE4119836-C2)      Electrolysis cell for gas-generating or gas-consuming processes has at least one electrode made up of elements (44,45) of foil with a quasi unidimensional or two-dimensional capillary structure in its reaction side edge region. Edges are profiled (51,52) with saw teeth, such elements alternating with unprofiled elements to give appropriate spacing. At least one capillary gap is formed for gas and electrolyte transport. Pref. elements are of Raney Ni.    ADVANTAGE -   Improved gas and electrolyte transport.
