Preparation of Ni/YSZ Anode Material using Gel-tape Casting and Performance Analysis

摘要

Ni/YSZ cermet is the most widely used anode material for solid oxide fuel cell.In this paper,the NiO/YSZ green body was prepared by gel-tape casting,using 15％wt.starch as pore-forming agent,in the mixed polyvinyl alcohol and acrylamide systems.Ni/YSZ anode material was obtained after sintered at 1450 °C for 2h and reduced at 800 °C in H2 atmosphere for 4h.The anode porosity,XRD,TGA and microstructures were measured.YSZ formed a continuous network structure and Ni particles were dispersed homogeneously in the YSZ network.It is suitable to fabrication of anode material for solid oxide fuel cell.
