摘要：

Bi2O3 doped BaFeO3-delta on the B-site as a cobalt free perovskite cathode for intermediate temperature solid oxide fuel cells is evaluated. The BaFe1-xBixO3-delta, (BFBx) powders are synthesized by solid state reaction. It is found that Bi2O3 doping stabilizes the BaFeO3 cubic phase. The new cathode is compatible with Gd0.1Ce0.9O1.95 even calcined at 1000 degrees C for 10 h. The electronic conductivity shows a transformation from semiconductor to metal conductor, and achieves its maximum value of 28.1 S cm(-1) for BFB10 at 800 degrees C. The 6 is as high as 0.408 for BFB10 determined by iodometric titration. This leads to the free volume in crystal lattice of BFB10 21.60% higher than that of BaNb0.05Fe0.95O3-delta. The area specific resistance is only 0.133 Omega cm(2) for BFB10 at 750 degrees C and the average TEC is 26.697 x 10(-6) K-1 measured from room temperature to 800 degrees C. The peak power density of Ni-YSZ|YSZ|GDC|BFB10 cell is 646.28 mW cm(-2) at 750 degrees C, higher than that of single cell using LSCF as cathode. These show that BFBx perovskite oxides with cubic phase are promising cathodes for intermediate temperature solid oxide fuel cells. (C) 2017 Hydrogen Energy Publications LLC.
