A method of improving performance of electrochemical gas sensors includes cycling potentials applied to one or more of the electrodes of the respective sensor(s) to improve performance of a different electrode. In a process for treating a reference electrode, potentials can be applied to working and, or counter electrodes so as to modify the environment in the vicinity of the reference electrode. An apparatus can carry out the method automatically.

Apparatus and method of regenerating electrochemical gas sensors

A gas sensor in one form comprises a housing including a base and a top defining an interior space. The housing includes a gas entry hole and first and second electrical terminals. First and second electrodes in the housing interior space each comprise a membrane having a layer of platinum black catalyst on one side. The second electrode includes a lower amount of platinum black catalyst than the first electrode. A separator is placed between the first and second electrodes. Current collectors electrically connect the first and second electrodes to the respective first and second electrical terminals whereby sensor current represents concentration of gas while minimizing cross sensitivity.
