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.

Bipolar electrolytic filter press cell frame

Electrolytic filter press cell frames are provided with a polymeric protective covering which is either directly laminated thereonto or otherwise secured thereto. The protective covering is, preferably, a fluorinated hydrocarbon.

Protective covering for electrolytic filter press cell frames

The central web of a bipolar electrolytic filter press cell has a plurality of nubs projecting therefrom to support the electrode and to maintain their flatness.

Electrode support for filter press cells

Segmented electrodes for use in electrolytic filter press cells obviate and reduce the problems of current distributions attributable to poor bipolar electrical connections, and electrode flatness. The electrodes are supported on the electrical boss as well as on the central barrier.
