Abstract

Die Erfindung betrifft eine Anordnung für eine Kathoden-Rezirkulation einer Brennstoffzelle (10) eines Brennstoffzellensystems (1) mit einer Kathodenversorgung (30) für die Brennstoffzelle (10), aufweisend einen Kathoden-Versorgungspfad (31) und einen Kathoden-Abgaspfad (32), und an die Kathodenversorgung (30) ein Spülkreis (50) eines Stapelgehäuses (16) der Brennstoffzelle (10) fluidmechanisch angeschlossen ist, wobei mittels eines RezirkulationsFluiddruckerzeugers (33, 53) in der Kathodenversorgung (30) und/oder im Spülkreis (50), ein Rezirkulationsfluid (7) in der Kathodenversorgung (30) und im Spülkreis (50) zirkulierbar ist. Ferner betrifft die Erfindung ein Verfahren zur Kathoden-Rezirkulation einer Brennstoffzelle (10) eines Brennstoffzellensystems (1) eines Fahrzeugs, insbesondere eines Elektrofahrzeugs, wobei ein Rezirkulationsfluid (7) durch einen Kathoden-Versorgungspfad (31), durch die Kathodenräume der Brennstoffzelle (10) und durch einen Kathoden-Abgaspfad (32) hindurchgefördert wird, und das Rezirkulationsfluid (7) ferner durch einen Spülkreis (50) für ein Stapelgehäuse (16) der Brennstoffzelle (10) sowie das Stapelgehäuse (16) hindurchgefördert wird.
