Abstract

Characteristics of slurry-coated Ni/YSZ cermet anode for solid oxide fuel cells (SOFCs) were investigated for the optimization of the anode microstructure. The anodic polarization of Ni/YSZ cermet was strongly affected by the particle-diameter ratio of raw materials rather than the particle size itself. The plot of polarization versus particle-diameter ratio of YSZ to Ni yielded a minimum at a particle-diameter ratio of around 2×10-2. From the density measurement of Cermet green bodies and EDX analysis, it was found that there was a strong correlation between the distribution of Ni in the cermet and the particle-diameter ratio. At the particle-diameter ratio which gave the minimum anodic polarization, Ni particles distributed most uniformly.
