(US4767519-A)      An electrolyser includes two electrodic end structures and an intermediate structure between them consisting of porous diaphragms or ion exchange membranes with separators on either side of it to divide the device into anode and cathode compartments. Electrolytes are fed to the compartments and electrolysis prods. are withdrawn. The intermediate structure comprises a current conducting and distributing core including a thin sheet(s) of highly conductive metal having several parallel, outwardly projecting ribs forming a channel. A pair of liners made of corrosion resistant metal are provided on each side of the core and having corresp. ribs fitting over the core ribs and having peripheral flanges. Planar electrode screens are connected to the liners. A frame is interposed between the flanges while the elements are all electrically connected.    USE/ADVANTAGE -   The filter-press electrolyser gives a uniform current distribution and is of light weight.    (RU2041291-C1)      Electrolyser comprises two electrodes, an intermediate electrode and a membrane separator between each electrode and the intermediate electrode to define anode and cathode compartments. The intermediate electrode comprises a highly conductive metal sheet core; parallel projecting ribs on one or both surfaces; corrosion resistance metal liners on each side of the core fitting the ribs or peripheral flanges on the core; and planar electrode screens fitted to the liners.    The core, ribs, liners and screens are all electrically connected and held by a peripheral frame.    USE/ADVANTAGE -   In industrial prodn. of O2, H2, Cl2, etc. Electrolyser provides uniform current distribution and is lightweight and is formed by a simple and economic process.    (JP2581685-B2)      Electrolyser comprises two electrodes, an intermediate electrode and a membrane separator between each electrode and the intermediate electrode to define anode and cathode compartments. The intermediate electrode comprises a highly conductive metal sheet core (1); parallel projecting ribs (2) on one or both surfaces; corrosion resistanc metal liners (3) on each side of the core fitting the ribs or peripheral flanges (4) on the core; and planar electrode screens (6) fitted to the liners.    The core, ribs, liners and screens are all electrically connected and held by a peripheral frame (5).    USE/ADVANTAGE -   In industrial prodn. of O2, H2, Cl2, etc. Electrolyser provides uniform current distribution and is lightweight and is formed by a simple and economic process.
