Resumen:
Micrometric layers of La0.4Sr0.6Co0.8Fe0.2O3-d (LSCF) nanostructured perovskite deposited by spin coating on a Ce0.9Gd0.1O2-d (CGO) electrolyte exhibited excellent polarization resistivities. Inaddition, this couple shows no diffusion or structural degradation, even after 1000 hours at 500ºC, being therefore an interesting material for IT-SOFC design. Moreover, it had been alreadyreported that depending on cathode morphology, the LSCF area specific resistance (ASR) mayvary more than two orders of magnitude for identical composition. In this work we explain partof that variation studying the electrode/electrolyte interface with SEM and TEM.
