An electrochemical gas sensor includes an electrolyte including at least one ionic liquid which includes an additive portion including at least one organic additive, at least one organometallic additive or at least one inorganic additive.

Electrochemical gas sensors with ionic liquid electrolyte systems

The invention relates to an electrochemical sensor including a housing with a chamber containing an electrolyte, at least one measuring electrode for oxygen detection, at least one counter electrode and at least one reference electrode, wherein the sensor has a two-part diffusion barrier, wherein a first part of the barrier forms a labyrinth with a second part of the barrier disposed between the measuring and the counter electrode.

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.
