Abstract | PrGa1-xMgxO3(x=0, 0. 05, 0. 10, 0. 15, 0. 20, 0. 25) were synthesized by using a standard solid state technology. XRD results show that all samples are orthorhombic. Mg-doping increases the oxygen ion conductivity and decreases the activation energy of the samples significantly. The conductivity of the samples is mainly ionic. PrGa0.9Mg0.1O3 has the highest conductivity of 0. 05 S/cm at 800 degreesC, while PrGa0.8Mg0.2O3 has the lowest activation energy of 24. 19 kJ/mol in all the samples. The oxygen ion transport number of the samples increases with increasing temperature. SOFCs results show that PrGa0.9Mg0.1O3 has the best properties, for which the power density of 0. 131 W/cm(2) and the short circuit current density of 0. 45 A/cm(2) were achieved at 940 degreesC. This study reveals that Mg doped PrGaO3 is a kind of solid electrolyte with superior properties. |
