Perovskite oxides such as lanthanum strontium cobalt ferrite are mixed electron-ionic conductors that have potential application as the electrocatalysts for oxygen reduction reaction in solid-state electrochemical devices including solid oxide fuel cells (SOFCs) for efficient energy conversion and membrane reactors for clean coal energy delivery. This work presents the kinetic enhancement through various oxides; doped ceria, barium carbonate, strontium oxide, calcium oxide, and transition metal oxides. For example, BaCO3 is demonstrated to to be effective in enhanceing the high temperature oxygen reduction reaction. At 700 °C, the area specific surface resistance for La0.8Sr0.2FeO3(LSF) on yttria-stabilized zirconia electrolyte decreases from 2.95 Ω cm2 to 0.77 Ω cm2 when 12.9wt% BaCO3 nanoparticles are infiltrated to the porous LSF electrode. By comparing the improving factors reported in the literatures, it is found that the catalytic activity is even higher than those for precious metals such as Pd, Rh, Pt and Ag.
