Abstract

 As high temperature fuel cells, solid oxide fuel cells (SOFCs) have the potential to be one of the cleanest and most efficient energy conversion of chemical fuels to electricity. One early technical opportunity is minimization of resistance to the oxygen reduction reaction (ORR) at the cathode, which contributes the most to performance degradation and efficiency loss in the existing SOFCs, especially at temperatures <700 °C.
In this talk, we will discuss surface modification method in enhancing SOFC electrode performance through wet- and thin film-based processes, focusing on two backbone architectures which are a porous mixed-conducting backbone and an active coating catalyst; the porous backbone provides excellent ionic and electronic conductivity, while the infiltrated surface coating possesses high catalytic activity and stability. Surface modification through infiltration is expected to play an increasingly important role in current and next- generation commercial SOFC development.
