Abstract
An electrochemical gas sensor includes an ionic liquid as electrolyte. The ionic liquid includes at least one cation selected from the group of a monoalkylammonium cation, a dialkylammonium cation, and a trialkylammonium cation. The individual alkyl groups of the cation can be branched or unbranched and have 1 to 4 carbon atoms. The individual alkyl groups of the cation can be the same or different in case of the dialkylammonium cation and the trialkylammonium cation. In a number of embodiments, the individual alkyl groups have 2 to 4 carbon atoms.
