Abstract
A fuel cell system having a plurality of electrochemical cells that are separated from one another by at least one bipolar plate, wherein a voltage-measuring module comprising at least one circuit board is provided for cell voltage measurement. Here, the bipolar plate is formed as an integral, supporting element of the circuit board of the voltage-measuring module.
Claims20
A fuel cell system comprising:
- a plurality of electrochemical cells which are separated from one another by at least one bipolar plate, and
- a voltage-measuring module having at least one printed circuit board being provided for cell voltage measurement,
- wherein the bipolar plate is designed as an integral, supporting element of the circuit board of the voltage-measuring module and the voltage-measuring module comprises an ASIC.
A method for operating a fuel cell system comprising:
- providing a fuel cell system having a plurality of bipolar plates separating the electrochemical cells from one another, wherein states of the electrochemical cells are detected by means of voltage-measuring modules which are each constructed on a bipolar plate as a circuit carrier,
- obtaining logical information with each voltage-measuring module based on voltage measurement values and only these are forwarded.
