Technique for reducing solid electrolyte cell drift

摘要

In a gas analyzer employing a disc-shaped oxygen ion conductive solid electrolyte cell, having electrodes disposed on opposite surfaces thereof, and secured at its edge within a tubular member by noble metal braze, a non-conducting ceramic layer is disposed between the solid electrolyte material and the braze to minimize cell drift which could otherwise occur if the braze interacted as a cell "electrode".
