Patent

CA 2447678

A flow field plate for a fuel cell has, on the front side thereof, flow channels for a reactant gas and at least two slots extending from the front thereof to the rear side. On the rear side at least two apertures are provided for the reactant gas and there is an aperture extension, providing a flow path from each aperture to a respective slot. This enables sealing surfaces, on the two sides to be offset so as to be fully supported. The arrangement avoids having to provide seal or gasket portions crossing flow channels and ensures that all portions of each gasket are properly supported.

L'invention concerne une plaque de champ d'écoulement pour pile à combustible, dont la partie avant est équipée de canaux d'écoulement pour gaz réactif, avec au moins deux fentes partant de l'avant vers l'arrière. A l'arrière, au moins deux ouvertures sont prévues pour le passage du gaz réactif, et il existe pour chaque ouverture une extension assurant un trajet d'écoulement entre l'ouverture et la fente correspondante. Une telle configuration permet de décaler les surfaces d'étanchéité, sur les deux côtés opposés, pour l'intégration parfaite de ces surfaces: ainsi, les trajets d'écoulement ne sont traversés par aucune partie de joint et chaque partie de joint est parfaitement intégrée.
