An electrochemical gas sensor ( 10 ) includes a housing ( 20 ) and with at least one electrode ( 21, 22 ). The housing ( 20 ) has a gas inlet ( 23 ). An at least strongly acidic, liquid electrolyte ( 30 ) is present in the gas sensor ( 10 ). The electrolyte ( 30 ) partly wets the electrode ( 21, 22 ). Provisions are made in such a gas sensor ( 10 ) for the electrolyte ( 30 ) to contain an additive that contains at least one surfactant. An electrolyte ( 30 ) is also provided for a gas sensor ( 10 ), which electrolyte ( 30 ) contains at least one surfactant as an additive. |
