[EN] Composites made of La0.8Sr0.2MnO3-delta (LSM) and lanthanide doped ceria (Ce(0.8)Ln(0.2)O(2-delta), Ln = Gd, Er, Tb and Pr) have been proposed as robust and high-performing solid oxide fuel cell cathodes. The addition of small amounts of highly-dispersed CoOx into the electrode promoted the formation of bridges among LSM-ceria particles. These resulted in the reduction of the required sintering temperature due to the enhancement of the sintering and proper ionic and electronic percolation pathways. In addition, Pr as a multivalent cation dopant in ceria showed the best electrochemical results toward oxygen reduction when the electrode sintering temperature is kept at 1000 degrees C.
