  • Electrode for electrolysis cells
    Patent number: 5589044
    Abstract: An electrode for mercury chlor-alkali electrolytic cells includes a plurality of activated electrode elements consisting of flat sections standing on edge and having recesses on their lateral surfaces which extend from the lower edge to the upper edge of the lateral surfaces. The recesses in the lateral surfaces promote the transport of the gas bubbles produced electrolytically away from the area of the electrode gap and achieve a boundary surface as free of gas bubbles as possible between the anode and the electrolyte in the area of the electrode gap for the purpose of improving the energy efficiency.
