(Invited) Compositional and Mechanical Stabilities of a (La,Sr)(Co,Fe)O3-δ Cathode under SOFC Operation

Compositional and mechanical stabilities of (La,Sr)(Co,Fe)O3 electrode are discussed in terms of possible kinetic decomposition under oxygen potential gradient in the electrode layer, The effect of the local oxygen potential change to the local stress and its effect, vise versa, on defect equilibriu...

Zusammenfassung:Compositional and mechanical stabilities of (La,Sr)(Co,Fe)O3 electrode are discussed in terms of possible kinetic decomposition under oxygen potential gradient in the electrode layer, The effect of the local oxygen potential change to the local stress and its effect, vise versa, on defect equilibrium will be discussed.
