As cathode electrocatalysts for alkaline anion exchange membrane fuel cells (AAEMFCs), La0.8Sr0.2MnO3+δ electrocatalysts were synthesized by Pechini's method at various heat treatment temperatures (HTT). With HTT increase from 600 to 900°C, the surface area gradually decreased 30.6 to 6.0m2g−1, while impurity phase was not detected for all HTTs. The specific activity for the oxygen reduction reaction...
