Abstract
Porous and electrically conducting Ni-YSZ cennet is used as
fuel electiOde for solid oxide fuel eel (SOFC). The synthesis of
NI-YSZ cermet through a solution chemistry route is
discussed in this paper. The Ni concentration is varied
between 10 and 60 volume percent (v/o). Porous structure of
these cnmets is obtained by p1·ope1· control of sintering
schedule. Electlical properties are evaluated as a function of
nickel content. At around 30 v/o of Ni a sudden change in
electrical conductivity takes place due to fm·mation of a
continuous Ni-chain.
