Abstract
A composite bipolar electrode structure is described. The structure includes an anode face comprised of a layer of a platinum group metal, metal oxide, or mixtures thereof, deposited on a layer of a valve metal, preferably titanium, a cathode face comprised of a cathode material, suitably a ferrous material, and an intermediate layer of conductive, porous material, such as graphite, positioned to be in electrical contact between the valve metal layer and the cathode material layer. The electrode is assembled by applying a thin layer of a polymeric material on the interfaces of the porous intermediate layers and pressing the components with sufficient pressure to force the polymeric material into the interstices of the intermediate layers.
