SOLID OXIDE FUEL CELL WITH OXIDE ANODE-SIDE

Solid oxide fuel cells (SOFCs) with anode-sid e supports, along with ZrO2 (YSZ) anode, YSZ electrolyte, and LSM-YSZ = La0.8Sr0.2MnO3) cathode, were prepared. Button yielded a power density up to 1 .0 W/cm2 in H2 and air at 800 C. The cells showed stability against coking in methane compared with Ni-...

Summary:Solid oxide fuel cells (SOFCs) with anode-sid e supports, along with ZrO2 (YSZ) anode, YSZ electrolyte, and LSM-YSZ = La0.8Sr0.2MnO3) cathode, were prepared. Button yielded a power density up to 1 .0 W/cm2 in H2 and air at 800 C. The cells showed stability against coking in methane compared with Ni-YSZ anode-supported SOFCs. A detailed m odel used to fit the SOFC electrical results and to that the good stability in methane was a result the high O-to-C ratio in the Ni-YSZ anode due to Sr0.8La0.2TiO3 support.
