Abstract

Low-temperature solid oxide fuel cells (LT-SOFCs) have attracted much attention for their long-term stability, short start-up time, and economic competitiveness. Development of a high electrochemical active cathode for the oxygen reduction reaction (ORR) is the key to LT-SOFCs. In this study, a cubic perovskite BaCo_0.7Fe_0.22Sc_0.08O_3–_δ (BCFSc) is synthesized and investigated. It exhibits extremely low polarization resistances (e.g., 0.03 Ω cm² at 600 °C) in symmetric cell using Ce_0.8Sm_0.2O_1.9 (SDC) as the electrolyte, indicating an excellent ORR catalytic activity. A maximum output power density of 1446 mW cm⁻² is achieved at 600 °C for a single cell with an anode functional layer, which is much larger than the one without it (1045 mW cm⁻²). The favorable performance enables BCFSc to be a candidate cathode for LT-SOFCs.
