Characteristics of Slurry‐Coated Nickel Zirconia Cermet Anodes for Solid Oxide Fuel Cells
Source abstract
Abstract
Polarization characteristics were studied in nickel and yttria stabilized zirconia cermet (Ni‐YSZ cermet) electrodes in order to search for an adequate fabrication condition of a planar solid oxide fuel cell. Several electrodes were prepared by the slurry coating method, and dc and ac polarization behaviors were investigated at 1273 K in atmosphere. An experimental equation was derived to describe a typical dc polarization curve of a Ni‐YSZ cermet electrode. Effects of fabrication temperature, nickel content, and material powder were investigated in terms of deviation from this equation. Anodic overvoltage with a carefully prepared electrode was decreased to about 0.12V at 1 A/cm 2 .
