Abstract

Abstract Electrochemical performance and degradation was analysed by conductivity measurements as well as thermogravimetric analysis (TGA) under different atmospheres. CO 2 was identified as a critical parameter in terms of carbonate formation from Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3–δ and causes a strong increase in the material resistivity, whereas La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3–δ is unaffected. The oxygen exchange kinetic of both compositions is affected by CO 2 containing atmospheres.
