Abstract

An electrochemical measuring cell for detecting oxidizing gases, containing an electrode with a redox mediator, which is oxidized by the gas to be detected. A measuring electrode is employed made of an inert material, and a counterelectrode is provided. The dynamics and reproducibility of the measured signal are improved by providing the counterelectrode formed of an anodically oxidizable material and is arranged behind the measuring electrode in the direction of diffusion in a sandwich-like arrangement.
