Abstract[English]
A bipolar plate includes a sheet having channels formed on a surface of the sheet, each channel including a header region, an active region, and an exhaust region. The channels are formed adjacent to each other and successively from a top side to a bottom side of the sheet. The active region is furcated into at least two active area channels along a longitudinal length of the active region from where the active region fluidically connects to the header region to where the active region fluidically connects to the exhaust region. A number of active area channels in the active regions of successive channels varies in one of a direction from the top side to the bottom side or a direction from the bottom side to the top side so as to achieve a uniform pressure drop and mass flow distribution across the plurality of channels.[French]
Une plaque bipolaire comprend une feuille ayant des canaux formés sur une surface de la feuille, chaque canal comprenant une région d'en-tête, une région active et une région d'échappement. Les canaux sont formés adjacents les uns aux autres et successivement d'un côté supérieur à un côté inférieur de la feuille. La région active est en outre disposée dans au moins deux canaux de zone active le long d'une longueur longitudinale de la région active à partir de laquelle la région active est en communication fluidique avec la région d'en-tête à l'endroit où la région active est en communication fluidique avec la région d'échappement. Un certain nombre de canaux de zone active dans les régions actives de canaux successifs varie dans l'une d'une direction allant du côté supérieur au côté inférieur ou d'une direction allant du côté inférieur au côté supérieur de façon à obtenir une chute de pression uniforme et une distribution de débit massique à travers la pluralité de canaux.
