Cobalt‐Free High‐Entropy Perovskite La0.2Pr0.2Nd0.2Sm0.2Sr0.2FeO3–δ Solid Oxide Cell Air Electrode With Enhanced Performance

“…High‐entropy perovskites (HEPs), containing five or more elements on the A‐ and/or B‐site of the perovskite structure ABO 3 , are an interesting material class that has emerged in recent years [14]. Their application as highly performing and long‐term stable air electrodes in SOCs has been successfully demonstrated for cobalt‐containing compositions [15–17]. The present study aims at showing that excellent performance and good long‐term stability can also be achieved with cobalt‐free HEP electrodes, provided that the cell design is optimized in terms of phase composition, microstructure, and current collection.…”
