Surface regulating and hetero-interface engineering of an LSCF cathode by CVD for solid oxide fuel cells: integration of improved electrochemical performance and Cr-tolerance

A conformal layer of CeO 2 on the surface of LSCF can be obtained using CVD. The fine-tuned CeO 2 /LSCF heterointerface and the suppressed Sr-segregation resulted in the improved electrochemical performance and enhanced Cr-tolerance of LSCF cathode.
