Polarization Promoted Chemical Reaction between Ba0.5Sr0.5Co0.8Fe0.2O3-δ Cathode and Ceria Based Electrolytes of Solid Oxide Fuel Cells

The chemical compatibility of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) electrodes with ceria based electrolytes is investigated under solid oxide fuel cell (SOFC) operation conditions. BSCF reacts with both Ce0.9Gd0.1O1.95 (GDC) and Ce0.8Sm0.2O1.95 (SDC) at 900°C, forming barium cerate (BaxCe1-yMyO3, where M...
