| Abstract | The oxygen incorporation/extraction kinetics of the potential solid oxide fuel cell (SOFC) cathode material Bi(1-x)Sr(x)FeO(3-δ) with x = 0.5 and 0.8 was studied by electrochemical impedance spectroscopy on geometrically well-defined pore-free thin film electrodes. The oxygen exchange rate was found to be higher than that of La(1-x)Sr(x)FeO(3-δ) and-among cobalt-free perovskites-only surpassed by Ba(1-x)Sr(x)FeO(3-δ) which is however known to be unstable in a SOFC environment. |
