摘要：

Solid oxide fuel cells with Sr0.8La0.2TiO3 anode-side Supports, Ni- Sm-doped ceria adhesion layer, NiY2O3 -stabilized ZrO2 (YSZ) anode active layer, YSZ electrolyte, and La0.8Sr0.2MnO3(LSM)-YSZ cathode are described. These cells are stable in simulated natural gas at current densities as low as 0.2Acm(-2). This represents much-improved stability against coking in natural gas, compared with conventional Ni-YSZ anode-supported SOFCs which rapidly coke, even at higher Current densities. Cell operation in H-2 fuel with 50-100 ppm, H2S results in an initial decrease in cell Power density, but no long-term degradation occurs and full recovery to the initial performance level is observed after dry H-2 fuel flow is restored. Degradation is not observed during or after seven redox cycles between H-2 and air. (c) 2008 Elsevier B.V. All rights reserved.
