Abstract
A fuel cell system (1), especially for motor vehicles, is provided with at least one fuel cell (2), which has at least two electrodes (3) for connecting at least one electric user (4). Simplified operation is achieved if a voltage-measuring device (5), for measuring an electric voltage at the electrodes (3), is provided and if a control (15) actuates an anode gas feed device (6) as a function of the measured voltage.
Claims20
A fuel cell system comprising:
- at least one fuel cell comprising at least two electrodes for connecting at least one electric user;
- a voltage-measuring device for measuring an electric voltage at said electrodes;
- an anode gas feed means for controlled supplying of said fuel cell with anode gas;
- and
- a control for actuating said anode gas feed means for supplying said fuel cell with anode gas depending on the electric voltage at the electrodes measured by said voltage-measuring device.
