Abstract
An electrode chamber unit intended for use in an electrochemical cell including at least one porous percolating electrode in the form of a bed of electrically conductive particles, e.g. of graphite. The unit is distinguished in that it includes at least one substantially flat frame (3), preferably of a polymeric material, said frame defining a central opening (4) which is filled with the electrically conductive particles so as to form a porous bed (5), the particles being kept in place in the central opening of the frame by sufficiently dense separators (10), preferably made from a polymer material, which are arranged to cover the central opening on either side of the frame to form an electrode chamber, that the frame is provided with at least one hole (8) for supply and at least one hole (9) for discharge of electrolyte, where said holes are in communication via supply and discharge channels with the central opening of the frame, and that the frame includes current conductors (6,7) for supplying electric current to the conductive particles. An electrochemical cell including the above-mentioned units. A method of producing the cell by placing a separator (13) horizontally, applying…
