Resumen

We investigated the electrochemical properties of Co–Fe perovskites, which can be used as cathodes for intermediate-temperature solid-oxide fuel cells (IT-SOFCs). We studied the electrochemical properties of nanostructured mixed ionic-electronic conductors for IT-SOFC cathodes with compositions of La_0.6Sr_0.4Co_1−yFe_yO₃ (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.
