英文摘要mixed ionic-electronic conducting (miec) oxides, srfeco0.5ox, srco0.8fe0.2o3-delta and la0.6sr0.4fe0.8co0.2o3-delta have been synthesized and prepared on yttria-stabilized zirconia as anodes for solid oxide fuel cells. power output measurements show that the anodes composed of such kinds of oxides exhibit modest electrochemical activities to both h-2 and ch4 fuels, giving maximum power densities of around 0.1 w/cm(2) at 950 degrees c. polarization and ac impedance measurements found that large activation overpotentials and ohmic resistance drops were the main causes for the relative inferior performance to the ni-ysz anode. while interlayered with an ni-ysz anode, a significant improvement in the electrochemical performance was observed. in particular, for the srfeco0.5ox oxide interlayered ni-ysz anode, the maximum power output reaches 0.25 w/cm2 on ch,, exceeding those of both srfeco0.5ox and the ni-ysz, as anodes alone. a synergetic effect of srfeco0.5ox and the ni-ysz has been observed. future work is needed to examine the long-term stability of miec oxide electrodes under a very reducing environment.
