Abstract
The novel perovskite material, SrSc0.175Nb 0.025Co0.8O3-δ, shows a rapid bulk oxygen diffusion rate below 550 °C (see oxygen movement indicated by the black arrow). Incorporation as an oxygen reduction cathode into a samarium-doped ceria fuel cell enables exceptionally high electrochemical performance, indicated by a power density of 910 mW cm-2 at 500 °C.
