Abstract
Abstract An electrolytic cell comprising a plurality of alternating, vertically disposed cathodes and anode plates, current lead-in metal bars connected to the lower ends of the anode plates, the metal bars and the lower ends of the anodes being embedded in and supported by a mass of electrically and thermally non-conducting rigid material such as concrete containing a chlorine resistant polyester resin. The anode plates may be comprised of a titanium type metal or alloy covered with an active layer containing a platinum group metal, alloy or compound. Included is means for feeding electrolyte to the cell while preventing unwanted flow of electricity through the feed ducts comprising a horizontal grooved disc for dividing the electrolyte into a plurality of radial droplet streams.
