COMPOSITE CATHODE FOR USE IN SOLID OXIDE FUEL CELL DEVICES

摘要

Disclosed are composite electrodes for use in a solid oxide fuel cell devices. The electrodes are comprised of a sintered mixture of lanthanum strontium ferrite phase and yttria stabilized zirconia phase. The lanthanum strontium ferrite phase has the general formula (LaxSry)i±d(FeaMnbCoc)O3; wherein l.O= x = 0.65; 0.35 = y = 0.0; x + y = 1.0, d=0-0.1, a+b+c=l, and a > 0.6.. Also disclosed are methods of making the composite electrodes and solid oxide fuel cell devices comprising same.
