The optimum composition of cathode catalyst has been studied for rechargeable zinc air battery application. La0.9Ca0.1Co1−xFexO3  (x=0–0.4)perovskite powders were prepared using the citrate method. The substitution ratio of Co2+with Fe3+cations was controlled in the range of 0–0.4. The optimum substitution ratio of Fe3+cations was determined by electrochemical measurement of the air cathode composed of the catalyst, polytetrafluoroethylene (PTFE) binder, and Vulcan XC-72 carbon. The substitution by Fe enhanced the electrochemical performances of the catalysts. Considering oxygen reduction/evolution reactions and cyclability, we achieved optimum substitution level ofx=0.1in La0.9Ca0.1Co1−xFexO3.
