Abstract

Solid oxide fuel cells (SOFCs) with Sr0.8 La0.2 Ti O3 anode-side supports, along with Ni- Y2 O3 -stabilized ZrO2 (YSZ) anode, YSZ electrolyte, and LSM-YSZ (LSM= La0.8 Sr0.2 Mn O3) cathode, were prepared. Button cells yielded a power density up to 1.0 W cm2 in humidified H2 and air at 800°C. The cells showed much-improved stability against coking in methane compared with conventional Ni-YSZ anode-supported SOFCs. A detailed model was used to fit the SOFC electrical results and to show that the good stability in methane was a result of the high O-to-C ratio in the Ni-YSZ anode due to the Sr0.8 La0.2 Ti O3 support.
