Solid oxide fuel cell (SOFC) is an energy conversion device that converts chemical energy stored in fuel and oxidizer into electrical energy. Since SOFC has some advantages of high efficiency, low product clean pollution and low noise, it thus becomes a hot research topic in recent years. The perovskite type of mixed electron-ion conductor is extensively investigated as a SOFC electrode material. In this paper, PrFe0.7Ni0.3O3-δ (PFN) with an orthorhombic structure was synthesized by a solid-phase method. The results show that the conductivity values are 46.500 and 0.007 S/cm in air and in H2, respectively, when PFN is at 800 ℃. The interfacial polarization impedance values are 0.08 and 0.24 Ω?偸cm2 in air and H2, respectively. The maximum power densities of the PFN/LSGM/PFN symmetric cell are 475 and 180 mW/cm2 at 800 ℃ when using hydrogen or ethanol as a fuel, respectively. It is indicated that Ni-doped PrFeO3 is a promising SOFC electrode material with the superior performance.
