ABSTRACT:
An improved electrical conversion device of the type comprising: (1) an anodic reaction zone containing a molten alkali metal reactant-anode in electrical contact with an external circuit; (2) a cathodic reaction zone containing a cathodic reactant comprising a liquid electrolyte which is electrochemically reactive with said anodic reactant and an electrode of porous conductive material which is at least partially immersed in said cathodic reactant; and (3) a cation-permeable barrier to mass liquid transfer interposed between and in contact with said anodic and cathodic reaction zones, said porous conductive material being in electrical contact with both said cation-permeable barrier and an external circuit; the improvement of the invention comprising a modification of the cathodic reaction zone of the device such that there are a plurality of channels and/or spaces within the zone which are free of the porous conductive material and which in combination with said porous conductive material are adapted to allow flow within said cathodic zone of the said cathodic reactant and cathodic reaction products during operation of the device.
