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 …

The carbon-coated Li3V2(PO4)3 was prepared by carbothermal reduction method.The structural and morphological properties of the material were studied by X-ray diffraction,FTIR and transmission electron microscopy.The synthesized material was a pure phase of Li3V2(PO4)3,with the particle size of about 100 nm.The values of Li ion diffusion coefficient of the material in the potential window of 3.0 ～ 4.3 V were nearly 3 orders larger than those in 3.0 ～ 4.8 V.In addition,the charge-transfer resistances in 3.0 ～ 4.3 V were much smaller than those in 3.0 ～ 4.8 V,leading to apparent improvement in cycling performance.This was mainly attributed to the smaller …
