A dense, conformal, thin‐film coating of Pr 0.75 Sr 0.2 MnO 3−δ (PSM) and PrSrCoMnO 6–δ (PSCM) on a state‐of‐the‐art La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3−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.
