dc.description.abstractEn | Sr1.5La0.5Mn1-xCoxO4 (SLMCOx) cathode materials for IT-SOFCs (intermediate temperature solid oxide fuel cells) were synthesized by EDTA-citric acid method and characterized by XRD, XPS and EIS, respectively. The results show that SLMCOx has no reaction with Ce0.9Gd0.1O1.95 at 1 200℃ for 12 h. Both the amount of Mn3+ and Co2+ in the oxide increase with the Co doping concentration; at the same time the content of lattice oxygen reduces, and the distortion ratio (c/a) of the lattice increases. The EIS results show that Co-doping dramatically reduces the polarization resistance (Rp) of SLMCOx cathode. The Sr1.5La0.5Mn0.7Co0.3O4 has the lowest Rp of 0.62 Ω·cm2 at 700℃ in air, which is clearly smaller than the Rp value of Sr1.5La0.5Mn0.7O4 that measured at 750℃ (1.5 Ω·cm2). Our results indicate that the Co doped Sr1.5La0.5Mn1-xCoxO4 is potential cathode material for IT-SOFC. | |
