摘要：

A BaO infiltrated La0.6Sr0.4Co0.2Fe0.8O3-delta ( LSCF) cathode shows remarkable tolerance and resistance towards chromium via the formation of BaCrO4 instead of SrCrO4 on the electrode surface, preventing the excess Sr deficiency at the A-site of LSCF perovskite and thus mitigating the Cr poisoning effect.
