  • the fuel cell can therefore only be used to generate energy if the HV battery is not fully charged.
  • the usable power of the fuel cell is very low at high battery voltages. This is due to the fact that when the battery voltage and power requirements are high, a current flow from the FC into the battery circuit results from the collapse of the battery voltage, but this is low due to the small voltage delta.
