  • Publication number: 20230366114
    Abstract: A control device (10, 20), for actuating an electrochemical gas generator cell (11), is configured to output a first control signal (Igen), which brings about the generation of an electrical operating voltage at the electrochemical gas generator cell (11), for an operating phase of the electrochemical gas generator cell (11). The electrical operating voltage is at least equal to an electrolysis voltage (Uele) of the electrochemical gas generator cell (11). The control device (10, 20) is further configured to output a second control signal (IRuhe, Upre), which brings about the generation of an electrical bias voltage (Upre) at the electrochemical gas generator cell (11), for a rest phase of the electrochemical gas generator cell (11). The electrical bias voltage (Upre) is lower than the electrolysis voltage (Uele). Further aspects pertain to systems (40a) and processes (50, 60, 70) for operating electrochemical gas generator cells (110).

  • Publication number: 20200326299
    Abstract: 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.
