ABSTRACT:
Unitary, cast structural element for filter press depolarized electrolysis cell which incorporates into a single unit the central barrier between the peripheral boundaries for the adjacent anode compartment and adjacent cathode compartment of two electrolysis cells located on opposite sides of the central barrier. At least one of such compartments also contains a gas chamber. An oxygen-containing gas may be fed into a depolarized cathode chamber or an hydrogen-containing gas may be fed into a depolarized anode chamber. Also incorporated into the single cast structural element are anode bosses and cathode bosses extending outwardly from opposite sides of the central barrier. These bosses not only serve as mechanical support for their respective flat plate anode and cathode, but also they serve as stand-off means and electrical current collectors and disperses from the cathode of one electrolysis cell to the anode of the next cell. Simplicity of design coupled with incorporation of many functional elements into one part eliminates many cell warpage problems, inherent high voltage problems and membrane "hot spot" problems.
