摘要：

Electrical conductivity of mixed conducting perovskite-type oxide, La1-xSrxCo0.2Fe0.8O3-delta (LSCF, 0.4 less than or equal to x less than or equal to 0.7) was determined as functions of Sr-content (x), temperature (T) and oxygen partial pressure [P (O-2)]. Crystal structure and oxygen nonstoichiometry (delta) of LSCF was evaluated and correlated with its electrical property. The electrical conductivity (sigma) in LSCF was greatly affected by oxygen nonstoichiometry and B-O-B angle (B; B-site elements) in the crystal.
