Abstract
Abstract Disclosed is a monopolar membrane cell in which identical anode and cathode pans are stamped from bimetallic laminate material in which an electrolyte resistant material is utilized on the inside of the electrolytic cell and a highly conductive metal is utilized on the outside thereof. This design results in a substantial lowering of the voltage drop due to resistance through the anode and cathode pans of membrane cells.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
144 words
A monopolar membrane-type electrolytic cell for electrolytic processes, the cell comprising: an anode chamber defined by said membrane, a generally planar foraminous titanium anode and a stamped metal laminate anode pan having an interior layer of titanium bonded throughout its extent to a thicker outer layer of aluminum; a cathode chamber defined by said membrane, a generally planar foraminous steel cathode and a stamped metal laminate cathode pan of identical form to said anode pan and having an interior layer of steel bonded throughout its extent to a thicker outer layer of aluminum; said cell further characterized in that each said anode and cathode pan affords a recessed chamber with a plurality of inwardly extending rib portions, each said rib portion being welded to said respective anode and cathode; and said anode and cathode are substantially parallel to and closely spaced from said membrane.
