Mechanisms of Performance Degradation of (La,Sr)(Co,Fe)O3-δ Solid Oxide Fuel Cell Cathodes

Symmetric cells with porous La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) electrodes on Gd0.1Ce0.9O1.95 (GDC) electrolytes were aged at 800°C for 800 hours in ambient air. Electrochemical impedance spectroscopy (EIS) measurements performed periodically at 700°C showed a continuous increase of the polarization res...
