METHOD FOR PRODUCING AN ELECTRODE THAT HAS A TEMPERATURE-STABILIZED CONDUCTIVITY

摘要

The invention relates to a method for producing an electrode to be used at high temperatures, according to which an electrode green compact is produced from a ceramic slip. Said slip is produced from at least one solid electrolyte material and a metal oxide powder. The green compact is dried and sintered. A porous hard granulate of the solid electrolyte material is used in the slip, the average diameter of the metal oxide powder particles not or substantially not exceeding the average diameter of the pores of the hard granulate. The inventive method provides an electrode that has a temperature-stabilized conductivity. The inventive electrode is typically used in high temperature fuel cells.
