Resumen:
We investigated the electrochemical properties of Co?Fe perovskites, which can be used as cathodes for intermediate-temperaturesolid-oxide fuel cells (IT-SOFCs). We studied the electrochemical properties of nanostructured mixed ionic-electronic conductors for IT-SOFC cathodes with compositions of La0.6Sr0.4Co1-yFeyO3 (y = 0.2, 0.5 and 0.8). We analyzed the performance of two types of nanostructures: nanorods and nanotubes. Our results show that the electrochemical performance is highly influenced by the form of nanostructure, whereas the effect of composition is less significant.
