Methods of synthesis were developed; nanosize two- and three-component Ru-based cathode catalysts RuM/C and RuMSe/C (М – Ni, Co, Fe, V) supported on carbon XC-72 were synthesized and analyzed. The effect of different precursors, metal ratio, synthesis conditions, and nature of the Fe-group metal on the catalytic system activity in the oxygen reduction reaction is studied. The studies were performed using the method of the rotating disk electrode (RDE) in 0.5M H2SO4 and at the temperature of 60°C.
