Abstract A filter-press-type Al/O2 battery with bipolar assembly of the electrodes was developed. The current-voltage curves and power output of monopolar and of bipolar batteries containing one to four cells were measured in alkaline (4 m NaOH and 7.5 M KOH) and acidic (3 m H2SO4 + 0.041 m HCl) electrolytes. The unit cell had an open circuit voltage of 1.85 V in alkaline media and 1.3 V in acidic media. The single bipolar unit delivered a maximum power of about 7.5 W (75 mW cm−2) at 0.7 V. The stack (four cells) had a maximum power of 30 W in 4 m NaOH and 35 W in 3 m H2S04 + 0.04 m HCl. The power output of the bipolar stack determined experimentally for different external loads could be described using the model of an electric equivalent circuit.
