Abstract

A novel composite cathode consisting of A-site disordered Pr_0.5Ba_0.5MnO_3-δ (PBM) and Er_0.4Bi_1.6O₃ (ESB) is developed for solid oxide fuel cells (SOFCs) with ceria-bismuth bilayer electrolyte. Based on Sm_0.075Nd_0.075Ce_0.85O_2-δ|ESB (SNDC|ESB) bilayer structured film, the single cell NiO-SNDC|SNDC|ESB|ESB-PBM achieves an encouraging performance with the maximum power density (MPD) of 994 mW cm^-2 and an interfacial polarization resistance (R_p) of 0.027 Ω cm² at 650 °C. Although a possible reaction between ESB and PBM has been identified in the cathode, the ascendant electrochemical performance including the very high fuel cell performance and R_p obtained here can demonstrate that the novel cobalt-free composite cathode ESB-PBM is a preferable alternative for ceria-bismuth bilayer electrolyte high performance low temperature SOFCs (HPLT-SOFCs) and the interfacial reaction in the cathode seems not to be detrimental to the electrochemical performance.
