The degradation mechanism of La0.6Sr0.4Co0.2Fe0.8O3 − δ (LSCF) electrode is investigated by examining its electrochemical behavior under equilibrium potential at elevated temperature and corresponding surface compositional changes. Diluted nitric acid etching treatment is conducted to confirm the co...
