SE371372

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.
