With an organic based tape casting processing, green NiO( Ni)/ SCO anode supports with 40%~80%Ni content were prepared and sintered at temperatures ranging from 1 200℃~1 450℃. The density and porosity were measured and the pore size and their distribution were checked by a N2 bubble point method for the green and sintered anode supports. The microstructure and electrical conductivity were also tested by scanning electron microscope (SEM) and with a four point technique, respectively. It was found that the porosity and pore size and their distribution were greatly dependent on the sintering temperature of green tapes, all of which decreased with increase of sintering temperature, consistent with the SEM observation. Furthermore, an increase of Ni content in the anode supports results in the decrease of porosity and mean pore size. It is also shown that the processing parameters as well as the Ni content play key roles in determining the electrical conductivity of Ni/SCO anodes.

以有机基流延工艺制备出了不同Ni含量的NiO/Sm0.2Ce0.8O1.9(NiO/SCO)燃料电池阳极支撑体膜。研究了制备工艺条件和Ni含量等因素对阳极膜微结构和性能的影响。试验结果表明:NiO/SCO流延生坯的烧结温度对最终阳极烧结体的孔隙特性有着决定的影响;为获得具有较高孔隙率和一定孔径分布的阳极烧结体,生坯的烧结温度应不超过1350℃;此外,不同含Ni量阳极流延生坯的烧结行为及烧结体的性能也存在明显的差异,在相同的烧结温度下,高含Ni量阳极烧结体的孔隙率和孔径都明显小于低含Ni量的烧结体,其晶粒的平均尺寸则增大。对不同温度下Ni/SCO阳极电导率的测量结果则表明,Ni/SCO阳极的导电性能也与其Ni含量和制备工艺有着密切的关系。

The cell performance was measured and impedance contributions were discussed.

A Ni-scandia-stabilized zirconia(Ni-ScSZ) cermet anode modified by coating with nano-sized gadolinium-doped ceria(GDC,Gd0.2Ce0.8O2) was prepared using a simple combustion process for the solid oxide fuel cell(SOFC) running on methane fuel.X-ray diffraction(XRD) and scanning electron microscopy(SEM) indicated that the surface of Ni-ScSZ was coated by nano-sized GDC particles(<100nm).Single cell testing showed that the 2.0%(by mass) GDC-coated Ni-ScSZ anode had better performance.The highest power densities of the cell with this anode were 825 and 848mW/cm2 at 850℃ in humidified hydrogen and methane,respectively,whereas the corresponding values were 584 and 586mW/cm2 for the cell with Ni-ScSZ anode.Electrochemical impedance spectra(EIS) illustrated that the cell with Ni-ScSZ anode exhibited far greater impedances than the cell with 2.0%(by mass) GDC-coated Ni-ScSZ anode.Then the short-term stability for the cells with the Ni-ScSZ and 2.0%(by mass) GDC-coated Ni-ScSZ anodes in 97%CH4/3%H2O at 700℃ was checked over a relative long period of operation.No significant degradation in performance has been observed after 84 h of cell testing when 2.0%(by mass) GDC-coated Ni-ScSZ anode was exposed to 97%CH4/3%H2O at 700 ℃.Very little carbon was detected on the anodes,suggesting that carbon deposition was limited during cell operation.
