  • Bipolar electrolytic filter press cell frame
    Patent number: 4051009
    Abstract: A cell frame for a bipolar electrolytic filter press cell includes an electrolysis-associated lower section and a gas disengagement or diverting upper section. A pressure bar extends across the cell frame immediately above the lower section to prevent distortion of the separator by cathode generated gases, and to promote disengagement of the gases. The frame, also, includes external headers in the upper section for collection of the gases evolved by the electrolysis of the electrolytic solutions.
