摘要	In this study, the valence state of Pr in Mg doped PrGaO3 perovskites was investigated. It is found that Pr4+ ions are created in samples doped with low-valence ions, for example, with Mg2+. The color of the doped samples changes from black to light green after being treated in H-2 atmosphere, which shows that the Pr4+ ions in the sample are reduced to Pr3+ ions. The open circuit voltage of the solid oxide fuel cell (SOFC) using PrGa0.95Mg0.05O3 as the electrolyte increases with time and the X-ray photoelectron spectroscopy (XPS) data of PrGa0.9Mg0.1O3 also show the existence of Pr4+ ions in Mg doped PrGaO3.
