Abstract

original image

A dense, conformal, thin-film coating of Pr0.75Sr0.2MnO3−δ (PSM) and PrSrCoMnO6–δ (PSCM) on a state-of-the-art La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)-based cathode for solid oxide fuel cells (SOFC) has drastically enhanced the electro-catalytic activity and stability of the cathode, suggesting that they are excellent electro-catalysts for surface modification of SOFC cathodes. The catalyst coating is introduced by a low-cost, one-step solution infiltration process.
