Abstract
Abstract In this study, perovskite La0.8-xBixSr0.2FeO3-δ (LBSF, x = 0.0–0.5) nanofibers with great crystallinity were prepared by electrospinning method and used as cathodes for intermediate temperature solid oxide fuel cells (IT-SOFCs). The symmetric cells of nanofiber-based LBSF electrode on Sm0.2Ce0.8O1.9 (SDC) electrolyte show excellent electrochemical performance. The La0.4Bi0.4Sr0.2FeO3-δ (LBSF4) cathode has the best performance with a polarization resistance (RP) of 0.126 Ω cm2 at 650 °C. The anode-supported single cell with LBSF4 as the cathode film and Ni-SDC as the anode has a maximum power density of 448 mW cm-2 at 650 °C using wet H2 as the fuel. In addition, the LBSF4 cathode with fibrous structure exhibits outstanding electrochemical behavior. The catalytic activity of the cathode was improved due to the incorporation of the Bi element, indicating that LBSF4 is promising as a cathode material in the field of IT-SOFCs.
