ABSTRACT:
An electrochemical gas sensor having a high surface area gas diffusing electrode defined for diffusing gases to be sensed to reach the catalyst surfaces of the electrode to provide the cathodic reduction of oxygen in a gas mixture undergoing sensing thereat. The sensor is adapted to sense trace levels of reactive gases in parts per billion. The sensor provides for ready purging of reactive gases from the electrolyte solution for the cell. The cell is essentially insensitive to the rate of flow of gas delivered to the cathode electrode and the minor mechanical stirring of the electrolyte solutions leading to output signals of improved signal-to-noise ratios more accurately signalling the concentrations of reactive gases, such as oxygen in gas mixtures.
