Abstract

Die Erfindung betrifft ein Brennstoffzellensystem (1) mit zumindest einer Niedertemperatur-Brennstoffzelle (2) mit einer kathodenseitigen Zuführleitung (5) für ein O2-hältiges Gas, vorzugsweise Luft, einer Abführleitung (6) für das Kathodenabgas, einer anodenseitigen Zuführleitung (7) für ein H2-hältiges Brennstoffgas, einer Abführleitung (8) für das Anodenabgas, sowie einer kathodenseitigen Rezirkulationseinrichtung (3) zur teilweisen Rückführung des Kathodenabgases in den Kathodenkreislauf der Brennstoffzelle (2). Um den Betrieb und die Regelungsmöglichkeiten zu verbessern weist die kathodenseitige Rezirkulationseinrichtung (3) einen Separator (9) zur Trennung des Kathodenabgases in eine flüssigwasserfreie Gasphase und Flüssigwasser auf, wobei für jede der beiden Komponenten zumindest eine separat regelbare Rezirkulationsleitung (10, 11) vorgesehen ist. Weiters kann in einer kathodenseitigen und einer anodenseitigen Rezirkulationsleitung (11, 14) jeweils ein in Abhängigkeit der Betriebsparameter des Brennstoffzellensystems aktivierbarer bzw. deaktivierbarer Flüssigwasser-Abscheider (30, 31) angeordnet sein.
