ABSTRACT:
An electrolytic diaphragm cell for the electrolysis of an aqueous solution of an alkali metal chloride is comprised of a cell body having a porous diaphragm separating the cell body into an anode compartment and a cathode compartment. The anode compartment contains at least one anode and the cathode compartment contains at least one cathode. The cathode is comprised of a formaminous metal conductor and a reticulate cathode, with the reticulate cathode being positioned between and in contact with the porous diaphragm and the foraminous metal conductor. The cell has means adapted to supply electric current to the anodes and the cathodes, nd inlets and outlets in the cell body adapted to supply and remove fluids. The electrolytic diaphragm cell of the present invention operates at reduced electrical power consumption by employing three dimensional cathodes having increased internal surface area and increased porosity.
