ABSTRACT:
An improved alkali metal/sulfur cell of the type including: (A) at least one anodic reaction zone containing a molten alkali metal reactant-anode in electrical contact with an external circuit; (B) at least one cathodic reaction zone including an electrode of porous conductive material and in which, during discharge of the cell, cations of the alkali metal combine with polysulfide or sulfur-saturated polysulfide ions to form reduced alkali metal polysulfide salts which at least partially fill said porous conductive material; and (C) 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 said external circuit. The improvement comprises adapting the cathodic reaction zone to operate as a gas fuel cell electrode by employing a sulfur storage chamber containing molten sulfur connected with said cathodic reaction zone so as to allow sulfur vapors to pass therebetween, the storage chamber being adapted to be maintained at a temperature
