Disclosed is a cermet electrode consisting of metal particles of nickel, cobalt, iron, or alloys or mixtures thereof immobilized by zirconia stabilized in cubic form which contains discrete deposits of about 0.1 to about 5% by weight of praseodymium, dysprosium, terbium, or a mixture thereof. The solid oxide electrode can be made by covering a substrate with particles of nickel, cobalt, iron, or mixtures thereof, growing a stabilized zirconia solid oxide skeleton around the particles thereby immobilizing them, contacting the skeleton with a compound of praseodymium, dysprosium, terbium, or a mixture thereof, and heating the skeleton to a temperature of at least 500°C. The electrode can also be made by preparing a slurry of nickel, cobalt, iron, or mixture and a compound of praseodymium, dysprosium, terbium, or a mixture thereof, depositing the slurry on a substrate, heating the slurry to dryness, and growing a stabilized zirconia skeleton around the metal particles.

A cermet electrode comprising: (A) metal particles selected from the group consisting of nickel, cobalt, iron, and mixtures thereof; (B) zirconia stabilized with yttria in cubic form immobilizing said metal particles; and (C) discrete deposits of an oxide selected from the group consisting of praseodymium oxide, dysprosium oxide, terbium oxide, and mixtures thereof, where the amount of praseodymium, dysprosium, and terbium in said discrete deposits is from about 0.1% to about 5% by weight of the weight of said cermet electrode.
