新型钙钛矿材料SrSc0.175Nb0.025Co0.803-δ在550C以下具有快速的体氧扩散速率(见黑色箭头所示的氧运动)。在掺Sm的CeO2燃料电池中加入氧还原阴极可以实现极高的电化学性能，在500℃时的功率密度为910 mW cm-2。版权所有
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.
