Abstract

The invention is directed to an electrochemical measuring cell to detect different gas components. The measuring cell includes several measuring electrodes (12, 15, 18) and a counter electrode 30 in an aqueous electrolyte 3. The measuring cell is improved with respect to the selectivity of the detection of the different gaseous components. A step-like offset 34 is provided between one of the measuring electrodes 12 and another measuring electrode 15.
