Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ)为阴极的中温固体氧化物燃料电池(英文)

Intermediate-Temperature Solid Oxide Fuel Cell with Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ)Cathode

通过在阴极与氧化钇稳定的氧化锆电解质间添加Gd0.1Ce0.9O1.95(GDC)隔层,成功地将Ba0.5Sr0.5Co0.8Fe0.2O3-δ(BSCF)阴极应用在中温固体氧化物燃料电池上.由BSCF膜的高透氧率可知,BSCF在中温范围内具有很高的氧离子电导率.在添加GDC隔层后,电池以空气为氧化剂时显示了很高的性能,极化电阻急剧下降,表明GDC隔层的添加是必要和有效的.

Anode-supported solid oxide fuel cells are of considerable interest due to their high power density, low area specific resistance and ability to use different fuels in the intermediate temperature range （650- 800 ℃ ）. Cathode polarization resistance is the main factor that limits the cell performance. It is necessary to develop high performance cathode materials to further improve the cell performance.
