Abstract

A mixed potential electrochemical sensor for the detection of gases has a ceria-based electrolyte(10) with a surface for exposing to the gases to be detected, and with a reference wire electrode(12, 24) and a sensing wire electrode(14, 22) extending through the surface and fixed within the electrolyte as the electrolyte is compressed and sintered. The electrochemical sensor is formed by placing a wire reference electrode and a wire sensing electrode in a die(20), where each electrode has a first compressed planar section and a second section depending from the first section with the second section of each electrode extending axially within the die. The die is filled with an oxide-electrolyte powder and the powder and the pressed oxide-electrolyte powder are sintered to form a ceramic electrolyte base with a reference wire and a sensing wire electrode depending therefrom.
