Abstract
Solid oxide full cell(SOFC) running directly on hydrocarbon fuels has attracted much attention in recent years.In this paper,a dual-layer structure anode was fabricated by tape casting and screen printing method.The addition of a LSCM-CeO2 catalyst layer to the supported anode surface yielded better performance in ethanol fuel.The maximum power density reached 710 and 669 mW/cm2 at 850 ℃ running on hydrogen gas steam and ethanol steam,respectively.No significant degradation in performance has been observed after 216 h of cell testing when the Ni-ScSZ13 anode was exposed to the ethanol steam at 700 ℃.Very little carbon was detected on the anode,suggesting that carbon deposition was limited during cell operation.Consequently,the LSCM-CeO2 catalyst layer on the supported anode made it possible to have good stability for long-term operation in ethanol fuel due to low carbon deposition.
