Abstract

PrGa_0.9Mg_0.1O₃ was synthesized by using a citric acid method. Compared with the sample prepared by the solid state technique, the sample synthesized by the citric acid method crystallized at a lower temperature. X-ray diffraction data indicated that a pure orthorhombic phase was formed at 1300 °C. PrGa_0.9Mg_0.1O₃ showed a conductivity of 0.076 S/cm at 800 °C and an activation energy of 32.98 kJ/mol. Its average thermal expansion coefficient from 600 to 1000 °C was 11.9 × 10^-6 K^-1, which well matches with the NiO/YSZ anode and doped LaMnO₃ cathode. A power density of 55 mW/cm² and a short circuit current density of 200 mA/cm² were obtained at 900 °C in a single fuel cell experiment by using PrGa _0.9Mg_0.1O₃ as an electrolyte. This could be attributed to the existence of hole conduction in the sample.
