A fuel cell assembly provides for direct water delivery to water injection points in the active area of fluid flow field plates of the assembly. The fluid flow field plate has a plurality of channels formed in the surface thereof which extend across the surface of the plate in a predetermined pattern, defining the active area of the plate. A distribution foil has a plurality of channels formed in a surface thereof which channels extend from a first edge of the distribution foil to a second edge of the distribution foil. The channels terminate at the second edge at positions substantially coincident with respective ones of the field plate channels at water injection points. A cover foil extends over the distribution foil to enclose the distribution foil channels and thereby form conduits for the water between the two foils.
La présente invention concerne un ensemble pile à combustible admettant la fourniture directe d'eau aux points d'injection d'eau dans la zone active des plaques de canalisation des fluides de l'ensemble. La plaque de canalisation des fluides comporte dans sa surface une pluralité de canaux qui occupent toute la surface de la plaque selon un tracé, ce qui définit la zone active de la plaque. L'ensemble comporte également une feuille de répartition comportant dans sa surface une pluralité de canaux allant d'un bord à l'autre de la feuille de distribution. Ces canaux arrivent à l'autre bord sensiblement en coïncidence avec ceux de la plaque de champ au niveau des points d'injection d'eau. Une feuille de couverture recouvrant l'ensemble de la feuille de répartition enferme les canaux de la feuille de distribution, formant ainsi des conduits pour l'eau entre les deux feuilles.
