Abstract

A series of samples Pr_0.6-xSr_0.4MnO₃ (x = 0, 0.01, 0.05, 0.1, 0.15, 0.2) were synthesized by a solid state reaction method. Pr deficiency at the A site has a great effect on the properties of Pr_0.6-xSr_0.4MnO₃ as the cathode of SOFCs (solid oxide fuel cells). Compared to the commonly used La_0.6Sr_0.4MnO₃ and La055Sr04MnO3 cathode, Pr_0.6-xSr_0.4MnO₃ is better in the properties of conductivity, overpotential and impedance. In all the samples, the one with x = 0.05, Pr_0.55Sr_0.4MnO₃, revealed the best performance in the measured temperature range.
