Degradation induced by sodium chloride in air was investigated for (La0.8Sr0.2)0.98MnO3(LSM) and La0.6Sr0.4Co0.2Fe0.8O3(LSCF) cathodes in solid oxide fuel cells(SOFC). Cell performance was measured by volatilizing NaCl to be supplied to the cathode at a constant current density of 200 mA/cm2 for up to 100 h. At 800 °C, an exposure of the cathode to 30 mg/L NaCl caused negligible degradation of LSM...
