Abstract

In the present study, La0.6Sr0.4Co0.2Fe0.8O3 (LSCF)-Gd0.1Ce0.9O1.95 (GDC) composite cathodes with different volume fractions were fabricated by the screen printing method, and their polarization characteristics and microstructure parameters are evaluated. Cathode overpotentials were measured at the measurement condition of 700°C and 100% O2. Microstructures were reconstructed by focused ion beam-scanning electron microscope (FIB-SEM). The relationship between polarization characteristics and microstructure is quantitatively investigated.
