Abstract

A method of testing a gas includes providing a sensor including a sensing electrode that includes a catalyst comprising palladium, and a counter electrode that includes a metal catalyst. An electrolyte is disposed between the sensing electrode and the counter electrode, and an external electrical circuit connects the sensing electrode and the counter electrode. The gas is contacted with the sensing electrode in the absence of a voltage bias applied to the sensing and counter electrodes. A capacitive response is detected that is produced by the exposure of the sensing electrode to the gas in the absence of a voltage bias applied to the sensing and counter electrodes.
