Nano composite of Ruddlesden-Popper electrocatalyst-oxygen ionic conductor, (Pr_0.9La_0.1)₂(Ni_0.74Cu_0.21Nb_0.05)O_4+δ (PLNCN)-Ce_0.9Gd_0.1O_2−δ (GDC), is developed as composite cathode for intermediate temperature solid oxide fuel cells (IT-SOFCs) via a infiltration way. The electrochemical behavior of PLNCN-GDC nanostructured electrode is assessed with respect to infiltration loading and oxygen partial pressure. The optimized PLNCN loading can improve charge transfer dynamics for electrochemical oxygen reduction reaction, thus promoting cathode performance. Importantly, the encouraging results of single cell highlight high activity and good CO₂ tolerance of PLNCN-GDC nanostructured cathode.
