Abstract
The electrode is made by depositing a slurry as a first layer onto a solid electrolyte ceramic of stabilized ZrO.sub.2. The slurry is a blend of a powder of a ceramic electronic conductor such as La.sub.1-x Ca.sub.x Mn.sub.1+y 03 or La.sub.1-x SR.sub.x Sr.sub.x Mn.sub.1+y 03 and a powder of a ceramic ionic conductor being of the same kind as the electrolyte. Onto the first layer a slurry of powder of the same ceramic electronic conductor used in the first slurry is deposited as a second layer. The layers are deposited by spray coating or dipping and are fired simultaneously thereafter or sequentially following respective application.
