Abstract

Crystallographically random surfaces of silver particles are reconstructed into low-index planes with low surface energy under a microwave-plasma treatment. The resultant silver decorated Ba0.5Sr0.5Co0.8Fe0.2O3−δ cathode shows a factor of 8 enhancement of the oxygen reduction reaction activity, achieving an area specific resistance of 0.17 Ω cm2 at 500 °C.
