Abstract
An electrochemical gas sensor () has a housing (), a working electrode (), a counterelectrode () and a reference electrode (). The housing () has an electrolyte reservoir (), a gas inlet orifice () and at least one gas outlet orifice (). The electrolyte reservoir () is filled with a liquid electrolyte (). The gas sensor () has a counterelectrode carrier (). The counterelectrode () is suspended on the counterelectrode carrier () in such a way that the counterelectrode () is suspended in the electrolyte reservoir () and the electrolyte () flows around the counterelectrode () on all sides. Preferably, the electrolyte includes (I) a solvent, e.g. water, propylene carbonate, ethylene carbonate or mixtures thereof; (ii) a conductive salt, especially an ionic liquid; and/or (iii) an organic mediator, for example substituted quinones, anthraquinones, etc.
