Warnock, D R

The structure of a cell for a metal--gas battery is disclosed. The cell components comprising the electrodes, separators, and electrolyte reservoirs are substantially planar structures, circular in shape and having a hole at the center. These components are stacked on a common axis perpendicular to their planar surfaces to form individual electrochemical cells. Individual cells may be similarly stacked to form a battery. The stack of flat ring-shaped components comprising a cell is enclosed in a plastic insulating cell case which provides a reactant gas manifold space at the inner circumference of the cell stack components inside the plastic enclosure. On the inner circumference of the plastic cell case are positioned ports covered with a non-wetting porous plastic membrane of Teflon. The porous membrane allows the reactant gas to pass freely through the port from the main axial reactant gas storage space in the center cavity of the cell into the manifold volume, but will not allow liquid electrolyte to pass through the membrane and escape from the cell stack. The cell (or battery) is enclosed in a conventional pressure vessel having conventional electrical connections. 3 figures.
