Abstract: A conceptual nickel – yttria stabilized zirconia (Ni/YSZ) cermet has been prepared by coating YSZ particles with metallic nickel using electroless coating technique. Concentration of nickel was varied between 5 and 60 volume %. Bulk samples were prepared by uniaxial pressing followed by sintering in the temperature range 1200 – 1350oC with a soaking time of 2-6 h. Thorough investigation on the electrical characteristics, thermal expansion behavior of the samples have been performed as a function of Ni-content in the cermet. Thermal expansion behavior and conductivity measurement results suggest that the samples prepared by this technique are suitable for solid oxide fuel cell (SOFC) anode application at Ni concentration as low as 20 volume %.
