Demonstration of 650°C operating high-performance metal-supported solid oxide fuel cell using Gd-doped CeO2 electrolyte, Ni anode and Sm(Ba0.5Sr0.5)Co2-xFexO5+δ- Ce0.9Gd0.1O2-δ cathode

Metal-supported solid oxide fuel cells (MS-SOFCs) exhibit numerous advantages, including thermal cycle stability, rapid start-up and lower costs. However, the slow oxygen reduction reaction (ORR) at the cathode, especially at...
