ABSTRACT:
An electrochemical gas sensor having a solid ionic conductive electrolyte therein and adapted to sense trace levels of reactive gases in the parts per million range. The electrochemical sensing cell has a pair of catalytic electrodes attached to the opposite sides of the solid electrolyte. The sensing cell is supported and contained to permit the distribution of reactant gases over the electrode surfaces for reacting thereat and thereby providing an external electrical current flow representative of the quantity of the reactant gas undergoing sensing.
