Abstract
An electrochemical gas sensor for detecting a specific gas being measured with a plurality of electrodes ( ), an electrolyte ( ) and a gas-permeable membrane ( ) has a reduced cross sensitivity with respect to interfering gases, a short response time and high sensitivity for the measured gas without the service life being reduced. The measuring electrode is a layer of doped diamond thin ( ) on a porous substrate ( ), where the gas-permeable memebrane is disposed over the measuring electrode to permit passage therethru of the gas being measured.
