摘要：

Cathodic overpotentials of Ln0.6Sr0.4MnO3 (Ln is La, Pr, Nd, Sm, Gd, Yb, and Y) were studied for a new cathode for solid-oxide fuel cells (SOFCs) with low overpotentials in a relatively-low-temperature region. Cathodic overpotentials strongly depended on the rare-earth cations in the A sites of the perovskite oxide. In particular, overpotentials of a Sr-doped PrMnO3 cathode maintained low values despite decreased operating temperature. Consequently, almost the same power density of a SOFC with La0.6Sr0.4MnO3 cathode was obtained at about 100 K lower operating temperature by using Sr-doped PrMnO3 as the catbode.
