Rational A‐Site Multi‐Cation Design Enables Durable Fe‐Based Perovskite Air Electrodes for Fast Oxygen Reduction

Although Pr 0.5 Ba 0.5 FeO 3–δ (PBF)‐based perovskite cathodes are prevalent for solid oxide fuel cells (SOFCs), their practical application is hindered by Ba 2+ surface segregation, causing structural degradation, and poor CO 2 tolerance. Here, Pr 1/6 La 1/6 Nd 1/6 Ba 1/6 Sr 1/6...
