Ludwig, F A

An improved electrical conversion device comprises the following: a container--current collector consisting essentially of an inner, load-bearing, high-strength, noncorrosive and electrically conductive ceramic member clad with a metal exterior; a cation-permeable barrier to mass liquid transfer which is disposed within container--current collector; a molten alkali metal reactant-anode within the anodic reaction zone; a cathodic reactant within the cathodic reaction zone; and a cathodic electrode. The improvement of the invention comprises adapting the metal-clad ceramic member of the device to serve not only as a container--current collector, but also as the cathodic electrode by shaping the metal-clad ceramic member such that the inner surface of the electrically conductive ceramic member is disposed in close proximity to at least a portion of the surface of the cation-permeable barrier, and that there are a plurality of open spaces for channels within the cathodic reaction zone through which the cathodic reactants may flow during operation of the device. 3 figures.
