摘要
Cathode materials Bat(1-x)Pr(x)CoO(3) (x = 0.3, 0.4, 0.5, 0.6) were prepared with wet chemical method. TG-DTA and sintering curves show that the materials were crystallized in a single perovskite phase at around 950 degrees C. The SEM images show that the prohibition of the particle growth and the decrease of the hole ratio were produced when the increase of Pr ions dopant to a certain quantity. The results of the single cell tests show that the fuel cell with the cathodes x =0. 5 have the best output performance and the greatest short current density and the maximum output power density, so it has more proper ratio than the other samples and fit Y3+ -doped BaCeO3 based solid electrolyte material perfectly.
