Abstract
Die vorliegende Erfindung betrifft eine Gasverteilerplatte die einen maeanderfoermig ausgebildeten Kuehlkanal fuer ein Kuehlfluid aufweist wobei die Hauptverlaufsrichtung des Kuehlkanals zweimal umgelenkt wird. Ebenso betrifft die vorliegende Erfindung eine Brennstoffzelle die eine erfindungsgemaesse Gasverteilerplatte umfasst.
The plate (100) has a gas distributor structure formed on a planar side of a fuel cell i.e. high temperature proton exchange membrane fuel cell. Meander-like cooling passages (10a, 10b, 10c) comprise an inlet opening (1) on a side of the plate located in an x-direction and an outlet opening (4) on another side of the plate facing the former side. The passages exhibit dual dimensioning in the y-direction with respect to dimensioning in the x-direction, where a main course direction of the passages is deflected twice by two deflections units (2, 3). Independent claims are also included for the following: (1) a method for operating a gas distributor plate (2) a fuel cell comprising a membrane electrode arrangement.
