N2 - A novel method by combining NAC-FAS (NAnometer-sized Crystal Formation in Alcoholic Solutions) method and mechanical milling treatment was successfully applied for dispersing perovskite type oxide LaMnO3 finely on carbon support. Microscopic observation revealed that nano-sized oxide particles were dispersed fairly well in the carbon support. The gas diffusion-type electrode prepared by means of reducing number and quantity of chemicals exhibited more excellent oxygen reduction activity than the electrodes containing LaMnO 3 prepared by RHP (Reverse Homogeneous Precipitation) method. It allowed current density as high as 300 mA cm-2 at -80 mV (vs. Hg/HgO) in 8 M KOH at 60 °C under air flow.
