Abstract

Abstract : The Mo-doping strategy allows the traditional Ba0.5 Sr0.5 Co0.8 Fe0.2 O3− 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. Abstract : Experimental studies integrated with first-principles calculation revealed that the Mo-doping strategy allows the traditional Ba0.5 Sr0.5 Co0.8 Fe0.2 O3− δ (BSCF) perovskite cathode to show improved hydration ability and proton migration ability, leading to a much larger power output when applied in fuel cells. In addition, the CO2 -tolerance ability of the material was improved with the Mo-doping strategy, suggesting that the new route coupled high performance with good stability and provided a promising way of designing a perovskite cathode for proton-conducting solid oxide fuel cells (H-SOFCs).
