Tailoring electronic structure of perovskite cathode for proton-conducting solid oxide fuel cells with high performance

Xi Xu et al.

Summary: The study demonstrates that tailoring the electronic structure of perovskite oxide with Mo-doping leads to improvements in cathode materials for proton-conducting solid oxide fuel cells. The Mo-doping changes the electronic structure of the oxide, making the metal-oxygen bond less strong and the surface more active towards oxygen reduction, resulting in more feasible oxygen vacancy formation critical for protonation. The electric field induced by Mo-doping provides an additional driving force for proton movement, accelerating proton migration in the oxide and improving cathode performance.
