ABSTRACT:
The present invention provides a unique solution to the problems of both steady-state and transient signals produced by a variety of interfering stimuli, including humidity, which relies upon the inclusion in a gas sensing electrode in an electrochemical gas sensor of a catalyst material in addition to a first catalyst material reactive to the target gas, the additional, or second, catalyst material producing a response to an interfering stimulus which is of the opposite polarity to that generated by the first catalyst material.
