ELECTRICALLY CONDUCTIVE FUEL CELL CONTACT MATERIALS |
摘要 |
A multilayer contact approach for use in a planar solid oxide fuel cell stack includes at least 3 layers of an electrically conductive perovskite which has a coefficient of thermal expansion closely matching the fuel cell material. The perovskite material may comprise La<SUB>1-x</SUB>E<SUB>x </SUB>Co<SUB>0.6</SUB>Ni<SUB>0.4</SUB>O<SUB>3 </SUB>where E is a alkaline earth metal and x is greater than or equal to zero. The middle layer is a stress relief layer which may fracture during thermal cycling to relieve stress, but remains conductive and prevents mechanical damage of more critical interfaces. |
