摘要: The invention discloses a modified solid oxide fuel cell cathode material and preparation method thereof, belonging to the technical field of catalytic preparation. includes following steps: mixing Er(NO ) .5H O, Bi(NO O complexing agent with de-ionized water, adjusting pH value, stirring components constantly fully dissolve components; heating solution, adding Sm Co Fe powder (x is 0.9-1.1, y 0-1) when solution becomes colloid, continuing obtain gel; drying calcining gel nano-structured composite material. technology simple stable. Nano-sized particles can be obtained at low cost. has both electronic conductivity ionic conductivity, nanostructure significantly improves surface reaction area cathode. Therefore, shows outstanding electrochemical activity.
