Abstract

Die Erfindung betrifft ein Verfahren zur Reinigung eines Rezirkulationskreislaufs (28) eines Brennstoffzellensystems (2) mit wenigstens einer Rezirkulationsfördereinrichtung (31) mit einem rotierenden Bauteil vor seiner Inbetriebnahme. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass die Rezirkulationsfördereinrichtung (31) ohne die aktive Zufuhr von Gas in den in Rezirkulationskreislauf (28) betrieben wird, wonach eine Absaugung des im Rezirkulationskreislauf (28) befindlichen Gasvolumens mittels Unterdruck erfolgt.
