The design for a rapidly-refuelable aluminum-air cell utilizing a solution-side current-collector (SSCC) was verified with a 50-cm/sup 2/ cell. Two rapidly-refuelable bicells were built with 200-cm/sup 2/ electrodes: the moving-anode design (Mark 1-1 cell) and moving cathode design (Mark 1-2 cell). The M1-1 cell was used for extensive parametric testing of anodes and air cathodes. The best cell performance was 3.66 kW/m/sup 2/ peak power density at 0.89V and 98.4% coulombic efficiency. Performance depends upon polarization of the air cathode since anode polarization losses are low. A full size, 1000-cm/sup 2/ cell (Mark 1-3) of the moving anode design was fabricated and satisfactorily demonstrated. Modeling of a 16-cell stack of the M1-3 design shows that shunt losses will be low (< 1.5%) and parallel electrolyte flow should be used.
