20090148742, Jun 11, 2009

Filed:

Dec 7, 2007

Appl. No.:

12/001062

Inventors:

Michael J. Day - Dublin OH, US
Scott L. Swartz - Columbus OH, US
Matthew M. Seabaugh - Columbus OH, US
Paul H. Matter - Columbus OH, US
Jared R. Archer - Marysville OH, US

International Classification:

H01M 8/10
H01M 4/58

US Classification:

429 33, 429223, 429220, 429304

Abstract:

Electrode materials systems for planar solid oxide fuel cells with high electrochemical performance including anode materials that provide exceptional long-term durability when used in reducing gases and cathode materials that provide exceptional long-term durability when used in oxygen-containing gases. The anode materials may comprise a cermet in which the metal component is a cobalt-nickel alloy. These anode materials provide exceptional long-term durability when used in reducing gases, e.g., in SOFCs with sulfur contaminated fuels. The cermet also may comprise a mixed-conducting ceria-based electrolyte material. The anode may have a bi-layer structure. A cerium oxide-based interfacial layer with mixed electronic and ionic conduction may be provided at the electrolyte/anode interface.
