| Abstract | Perovskite Ba0.8La0.2FeO3-delta was synthesized via a glycine-nitrate process as the cathode material for intermediate-temperature solid oxide fuel cells. Ultra-fine pure phase Ba0.8La0.2FeO3-delta powder was obtained after the self-propagating combustion of a complex xerogel precursor. The Ba0.8La0.2FeO3-delta cathode showed good compatibility and an enhanced phase interface with a samarium-doped ceria electrolyte. Electrochemical measurements showed that the Ba0.8La0.2FeO3-delta cathode achieved a low polarization resistance of 0.58 Omega cm(2) at 800 A degrees C in an air atmosphere. The porous nanostructure guaranteed the catalytic activity for the oxygen reduction reaction, even if the cathode material possessed a cobalt-free and low rare earth composition. <br> <br>[GRAPHICS] <br> <br>. |
