Mo-doping allows high performance for a perovskite cathode applied in proton-conducting solid oxide fuel cells

The Mo-doping strategy allows the traditional Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3− δ (BSCF) cathode to show improvements in hydration ability, proton migration ability and chemical stability, leading to high performance of the fuel cell with good stability.
