Abstract:
An electrode structure comprising(i) a pan with a dished recess and a flange around the periphery thereof for supporting a gasket capable of sealing a separator between the surface of the anode of a first electrode structure and the cathode of a second structure such that the anode surface is substantially parallel to and faces but is insulated and spaced apart from the cathode surface by the separator and is hermetically-sealed to the separator; (ii) an electrically conductive plate spaced from the pan; (iii) an inlet for liquor; and (iv) an outlet for fluids; wherein the plate is electrically connected to the pans by electrically conductive pathways between the pan and the electrically conductive plate with the proviso that, where the plate is an anode plate, it may optionally be directly electrically connected to the pan; and wherein, where the electrode structure is a cathode structure, the dished recess is provided with a plurality of outwardly projecting projections such that the inwardly projecting projections in the dished recess of the pan of the anode structure mate with the outwardly projecting projections in the dished recess of the pan of an adjacent cathode structure in an assembly comprising a plurality of the electrode structures.
