Air cathodes were evaluated to determine polarization characteristics and the effect of aluminate, stannate and carbonate concentration. Tests confirmed prior measurements by Electromedia Corporation (EMC) that polarization is about 30 mV/kAm/sup -2/ at the electrode surface. Air cathodes from another vendor exhibited comparable performance. Variation in electrolyte composition caused on only small changes (<10%) in cathode performance. The rapidly-refuelable, subscale Mark 1-2 Aluminum-Air battery (moving cathode) was evaluated. Peak power density was measured at 2.7 and 3.1 kW/m/sup 2/ which is similar to performance of the Mark 1-1 cell. Fabrication of the rapidly-refuelable, 6-cell module with 200-cm/sup 2/ moving anodes was partially completed.
