A Cobalt‐Free Multi‐Phase Nanocomposite as Near‐Ideal Cathode of Intermediate‐Temperature Solid Oxide Fuel Cells Developed by Smart Self‐Assembly

An ideal solid oxide fuel cell (SOFC) cathode should meet multiple requirements, i.e., high activity for oxygen reduction reaction (ORR), good conductivity, favorable stability, and sound thermo-mechanical/chemical compatibility with electrolyte, while it is very challenging to achieve all these requirements based on a single-phase material. Herein, a cost-effective multi-phase nanocomposite, facilely synthesized through smart self-assembly at...
