Abstract
An electrochemical gas sensor system () detects the concentration of a harmful gas in a measuring environment (). The electrochemical gas sensor system () contains a voltage generator () and an electrochemical gas sensor (). The electrochemical gas sensor () has a sensor housing () and a gas inlet (). A measuring electrode (), an auxiliary electrode (), a reference electrode (), a first generator electrode () and a second generator electrode () are in an electrolyte liquid () in the sensor housing (). A salt () (halide) of a halogen is dissolved in the electrolyte liquid (). The first generator electrode () and the second generator electrode () are connected to the voltage generator () to form a galvanic source. The galvanic source causes the salt () (halide) to react to form a halogen ('). A defined, largely stable reference voltage potential becomes established on the reference electrode ().
