ABSTRACT:
An electrochemical cell is shown wherein anode 1 of a reactive metal having an insulating film 2 thereon is separated from cathode 6 by a non-conductive flow screen 4. A porous, expandable element 5 is positioned between screen 4 and cathode 6 to maintain essentially uniform dimensions of the electrolyte flow channel defined by screen 4 as the anode is consumed during cell operation. Preferably, when a multiplicity of cells are electrically connected together, a plurality of separator elements 8 between the respective anodes and cathodes are utilized to ensure that each cell in the multi-cell configuration is subject to essentially identical compression forces in assembly and during discharge.
