Abstract
A minor amount of CO2 in air usually causes a detrimental effect on oxygen activation over a solid oxide fuel cell (SOFC) cathode because insulating surface carbonate is easily formed, which inhibits charge transfer during the oxygen reduction reaction (ORR). In this study, we report that the detrimental effect due to the CO2 interaction with perovskite oxide can be turned into a beneficial effect for facilitating ORR through tailoring the...
