Abstract—10 at.% ceria-substation on A-site for
La0.75Sr0.15Ce0.1Cr0.5Mn0.5 (noted as LSCCM) was synthesized
by the sol-gel process. The characterizations were done by XRD
and SEM. The structures, before and after exposure to 5%
H2S-5% wet H2 at 900 ℃, were demonstrated using X-ray
diffraction (XRD). And best sulfur tolerance of LSCCM was
studied. It also demonstrated that LSCCM had good structural
compatibility with electrolyte YSZ. SEM test exhibits a
homogeneous distribution of pores. The results of electric
performance test prove that the maximal power density was
16.03 mW·cm-2 in 5% H2S-5% wet H2 at 900 ℃.
Index Terms—Symmetrical electrode, ceria-substation,
