ABSTRACT OF THE DISCLOSURE ELECTROCHEMICAL CELL AND METHOD FOR THE DETECTION OF NOXIOUS GASES The present invention is for an electrochemical cell and method for quantitatively detecting noxious gas which comprises a first working electrode comprising a gas diffusion membrane having bonded thereto a catalytic portion electrochemically reactive with the noxious gas; a second working electrode having electrochemical activity with the oxidation/reduction products produced at the first working electrode; a counter electrode; a reference electrode; an electrolyte; means for containing said electrolyte and said electrodes; means for maintaining a fixed potential on said first working electrode relative to said reference electrode of from about 1.0 to 1.8 volts with respect to the potential of the reversible hydrogen couple of the electrolyte of the cell; and means for maintaining a fixed potential on said second working electrode relative to said reference electrode of from about 1.0 to 2.2 volts with respect to the potential of the reversible hydrogen couple of the electrolyte of the cell, the fixed potential on said working electrode being maintained at a voltage higher than the fixed potential being maintained on said first working electrode.
