  • control unit is designed such that the first recirculation line is shut off and optionally the electrical bypass line around the first fuel cell is switched to active in the event of a down-transient or if a current intensity value falls below a predetermined value.

  • the first recirculation line 6A comprises a recirculation blower 3 or a recirculation pump, which is advantageously of explosion-protected construction and open-loop controlled via a control unit of the fuel cell system.
  • the recirculation blower 3 promotes the recirculation of unreacted and thus unused fuel in the recirculation line 6A, whereas the ejector 2 on the other hand promotes the recirculation of unused hydrogen in the recirculation line 6B.

  • a further possible way of removing inert gases from the recirculation circuit may proceed by means of a gas purge line, not illustrated, which is located upstream of the air inlet of the fuel cells 4.
  • a particular disadvantage in this respect is that during "purging" some of the hydrogen is lost, so reducing the efficiency of the fuel cell arrangement 4.
