Abstract

Nickel-titania doped yttria stabilized zirconia(Ni/YZT) cermets for solid oxide fuel cell anodes were fabricated using nickel oxide titania doped yttria stabilized zirconia(NiO-YZT) composites with 40% Ni content, prepared by an economical energy-saving microwave processing technique. NiO-YZT composites were reduced in H2/Ar (5%/95%) atmosphere for 5 hours at 800°C. The reduced products were characterized by x-ray diffractometer (XRD), scanning electron microscope (SEM), vickers indentation and impedance spectroscopy. XRD patterns indicated Ni peaks. SEM showed increasing porosity with Ti content due to which vickers hardness decreased as compared to precursor NiO-YZT. Ni-YZT cermet anodes exhibited greater electrical conductivity than Ni-YSZ cermet anodes.

Keywords: Ni-YZT, NiO-YZT, XRD, SEM, impedance spectroscopy
