Title (EN) FOLDED METAL BIPOLAR SHEETS FOR FUEL CELLS
(FR) FEUILLES METALLIQUES BIPOLAIRES PLIEES POUR PILES A COMBUSTIBLE
Abstract: front page image
(EN)In a fuel cell stack, a bipolar separator plate having two joined together coextensive separator plate elements having perpendicularly disposed corrugated regions and forming a coolant chamber there between. By virtue of this arrangement, fuel and oxidant gases fed to the fuel cell stack have a cross-flow relationship. Internal stack manifolding is provided for distribution of a coolant to each of the coolant chambers.
(FR)L'invention concerne un empilement de piles à combustible, dans lequel une plaque séparatrice bipolaire comporte deux éléments de la plaque coextensifs réunis présentant des zones ondulées disposées perpendiculairement et formant entre elles une chambre de refroidissement. Grâce à cette disposition, le combustible et les gaz comburants injectés dans l'empilement de piles à combustible présentent une relation d'écoulement transversal. Un raccordement au collecteur interne de l'empilement est réalisé aux fins d'alimenter en caloporteur chacune des chambres de refroidissement.
