Gelcasting and dry pressing are used to produce anode composites for SOFC. In this paper a composite material Ni/Ce-YSZ containing Ni and Ce-doped Y2O3-stabilized ZrO2 (Ce-YSZ) based on Ce-YSZ electrolyte was fabricated via sintering infiltration of NiO at the temperature of 1400°C, followed Ni/Ce-YSZ materials are successfully produced by reduction- sintering process. Hydrogen reduction of NiO in the NiO/Ce-YSZ anode material was accomplished successfully through pore channels of debinded carbon volume. XRD results suggest that a solid solution of Ce-YSZ was produced. The microstructure of NiO/Ce-YSZ, and Ni/Ce-YSZ material was observed by SEM. This study confirms that sintering infiltration of NiO is a viable process for fabricating anode materials based on zirconia electrolyte and there are a good interface between electrolyte and anode.
