Abstract
(A1) Die Erfindung betrifft eine Brennstoffzellenanordnung. Erfindungsgemaess weist die Brennstoffzellenanordnung mindestens einen zwischen einem Brennstoffzellenstack und einem Gehaeuse verlaufenden Kuehlkanal auf, welcher einen Einlass und einen Auslass zum Erzeugen eines Gasstromes im Kuehlkanal aufweist. Mithilfe der Erfindung ist es moeglich, mittels einer Belueftungseinrichtung einen Gasstrom zur Kuehlung und gleichzeitig zur Belueftung der Kathode zu verwenden.

 

DE 102009022946 A1 UPAB: 20101122 NOVELTY - The system has a fuel cell stack arranged in a housing, and fuel cells i.e. bi-fuel cells, including respective active regions with a cross sectional area smaller than cross-sectional surface of the housing. The fuel cells are arranged perpendicular to a stack direction i.e. z-direction, in cathode channels (12) for cathode-sided gas exchange. A cooling channel (20) extends between the fuel cell stack and the housing in an x-direction and is provided with an inlet (22) and an outlet (24). The cathode channels are connected with the cooling channel. USE - Fuel cell system e.g. direct methanol fuel cell system and proton exchange membrane fuel cell system (all claimed) for a vehicle. ADVANTAGE - The system exhibits high power density and compact size, and is manufactured at low cost.
