Highly sulfur poisoning-tolerant BaCeO3-impregnated La0.6Sr0.4Co0.2Fe0.8O3−δ cathodes for solid oxide fuel cells
© 2018 IOP Publishing Ltd. Electrochemical performance and sulfur (SO2) tolerance were studied on pristine La0.6Sr0.4Co0.2Fe0.8O3-d(LSCF) and BaCeO3-impregnated LSCF (BaCeO3-LSCF) composite cathodes of solid oxide fuel cells (SOFCs). Compared to pristine LSCF electrodes, BaCeO3-LSCF composite electr...

| description | © 2018 IOP Publishing Ltd. Electrochemical performance and sulfur (SO2) tolerance were studied on pristine La0.6Sr0.4Co0.2Fe0.8O3-d(LSCF) and BaCeO3-impregnated LSCF (BaCeO3-LSCF) composite cathodes of solid oxide fuel cells (SOFCs). Compared to pristine LSCF electrodes, BaCeO3-LSCF composite electrodes exhibited reduced electrode polarization resistance and significantly lower activation energy for the O2reduction reaction, indicating that BaCeO2impregnation is effective at promoting the electrocatalytic activity of LSCF electrodes at low temperatures. Most significantly, BaCeO3-LSCF cathodes show remarkable tolerance and resistance towards sulfur via the formation of BaSO4instead of SrSO4on the electrode surface, preventing excess Sr deficiency at the A-site of LSCF perovskite and thus mitigating the sulfur poisoning effect. BaCeO3-LSCF cathodes show potential as highly active and excellent anti-sulfur oxygen electrodes for SOFCs. |
