Title:
【発明の名称】電気化学的ガスセンサで使用する改良センサ電極
Document Type and Number:
Japanese Patent JP2989558
Kind Code:
B2
Abstract:
A sensing surface for a sensing cathode electrode useful in electrochemical gas sensors for sensing active gases in a gas mixture. The gas sensors are utilized in sensing oxygen or exhaust gases from a motor vehicle, so that there is a potential for causing deposits on the sensing surface of the electrode of either lead oxide species or lead carbonate thereon. The sensing surface is plated with rhodium or platinum for rejecting or prolonging the formation of any of the deposits thereon leading to an increase in rated life for the gas sensor greater than heretofore thought possible.
