Abstract
Oxygen reduction performances of gas-diffusion type carbon electrodes loaded with perovskite-type oxides La1−xCaxMO3 (M=Co,Mn) were examined in 30 wt% KOH at 25 °C. The highest electrode performance, i.e., 2600 mA/cm2 at −125 mV vs. Hg/HgO, was obtained with large surface area La0.6Ca0.4CoO3 prepared by an amorphous precursor method.Keywords
