摘要
The use of a dense film to modify perovskite is a new approach to develop highly stable cathode for solid oxide fuel cell (SOFC). Here, we report that La0.8Sr0.2MnO3 (LSMO) surface decoration led to markedly enhanced stability and activity of conventional Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF). This novel cathode architecture has a potential to make effective use of the desirable properties of two different materials: the high oxygen ionic conductivity of a BSCF backbone and the excellent stability and high catalytic activity of an LSMO film-coating. An optimized impregnation technology was used to prepare a uniform and continuous LSMO nano-film into BSCF porous cathode.
