Abstract

In einem Brennstoffzellensystem gibt es einen Startheizer (34) zum Beheizen eines Kühlmittels bei einem Kaltstart. Erfindungsgemäß wird die von dem Startheizer (34) bereitgestellte Wärme zum Beheizen weiterer Bauteile bei einem Kaltstart genutzt. Die weiteren Bauteile können ein Dosierventil (16) sein, über das Wasserstoff einer Brennstoffzelle zugeführt wird, ein Abscheider (24) für Wasser auf der Anodenseite oder eine Pumpe (26) zur Zufuhr von nicht verbrauchtem Wasserstoff in eine Zufuhrleitung (14), oder es können beliebige Leitungen (14, 18, 40a, 40b, 40c) von dem Startheizer (34) erwärmt werden. Die Bauteile können in eine Endplatte eines Brennstoffzellenstapels integriert sein.
