Abstract

The zinc-air electrochemical system in 5m NH4Cl was studied. The optimum electrolyte-zinc ratio was found to be 50 ml g−1 Zn and the optimum electrolyte-cathode ratio, 15 ml cm−2 of carbon cathode. The air cathode polarization is not increased by intermittent usage of the cell. Electrodes made from zinc sponge with addition of lead show the smallest corrosion in the given electrolyte. The cell voltage is about 0.9–0.95 V at a load of 10 mA cm−2 of carbon cathode at ambient temperature.
