Time-dependent performance changes in LSCF-infiltrated SOFC cathodes: The role of nano-particle coarsening

Symmetric solid oxide cells with Gd doped ceria (GDC) electrolytes and La 0.6Sr 0.4Co 0.2Fe 0.8O 3 – δ (LSCF)-infiltrated-GDC cathodes were maintained in air with no current at temperatures from 650 to 850 °C. Comparison of SEM images before and after aging showed inhomogeneous coarsening of LSCF na...
