Abstract: An improved anode and base assembly for diaphragm type electrolytic cells is disclosed. In the present embodiment, downwardly facing annular portions at the base of the anode risers of dimensionally stable anodes of the type well-known in the art are welded from below directly to a metal cell base cover which seals the electrolyte contained within the cell from the cell base which is generally of copper or aluminum, thereby eliminating corrosion problems associated with leaks in the rubber gaskets or blankets formally used between the anode risers and the cell base.

Abstract: Relates to anodes for electrolytic cells, for the electrolysis of brine solutions, having primary lead-in means of high conducting capacity (copper) for supplying anodic current to the cell from outside the cell and connected to a current supply source, primary conducting means of lower conducting capacity (titanium, or tantalum or alloys thereof) inside the cell, secondary conducting means of lower conducting capacity (titanium, or tantalum or alloys thereof) inside the cell for conducting current to an electrocatalytically active coating carried on a valve metal base, said electrocatalytic coating being capable of catalyzing halogen ion discharge without becoming passivated over long periods of time, said anodes serving to distribute the current in a cascade fashion from the primary lead-ins to the anode face.
