dc.description.abstract | The reducibility of B-site elements in perovskite (ABO3) structures is one of the paramount factors that promote the in-situ exsolution of metallic nanocatalysts, and the phase transition of the support to a more stable structure under solid oxide cell (SOC) fuel electrode operating conditions. Herein, we develop a highly catalytically active and durable perovskite-based fuel electrode material—La0.6Sr0.4Co0.15Fe0.8Pd0.05O3- δ (LSCFP)—for reversible SOCs. The LSCFP material under the fuel electrode condition is fully transformed into a stable Ruddlesden-Popper phase decorated by bimetallic Co-Fe nanocatalysts. The SOC with LSCFP fuel electrode yielded outstanding performances in both fuel cell (2.00 W cm−2) and electrolysis cell (2.23 A/cm2 at 1.3 V) modes at 850 °C, with remarkable reversible-cyclic stability. These results clearly demonstrate that the novel LSCFP capable of concurrent phase transition and bimetallic exsolution in the reducing condition is a highly prospective candidate as a bifunctional fuel electrode for reversible SOCs. © 2022 Elsevier B.V. | - |
