Abstract:
1. A method for fabricating a mixed potential electrochemical sensor for the detection of gases comprising: forming a wire reference electrode and a wire sensing electrode, each electrode having a first compressed planar section and a second section depending from the first section; placing the wire electrodes in a die with the second section of each electrode extending axially within the die; filling the die with an oxide-electrolyte powder; pressing the powder with the wire electrodes; removing excess oxide-electrolyte powder to expose the first compressed planar portion of the electrodes; extending the first portion of the electrodes axially from the pressed oxide-electrolyte powder; and sintering the wire-electrodes and the pressed oxide-electrolyte powder to form a ceramic electrolyte base with a reference wire electrode and a sensing wire electrode depending therefrom.
