A corrosion resistant coated fuel cell plate and method of making the same are embodied in a metal plate (400) provided with a graphite emulsion coating (402) and then a layer (406) of graphite foil which is pressed over the coating (402). The graphite emulsion (402) bonds the graphite foil (406) to the metal plate (400) and seals fine scale porosities (410) in the graphite foil (406). Flow fields (414) are formed by stamping the coated fuel cell plate.
La présente invention concerne une plaque de pile à combustible à revêtement anticorrosion et un procédé de fabrication de celle-ci. Cette plaque (400) est en métal revêtue (402) d'une émulsion de graphite, puis d'une couche (406) d'un film de graphite pressé sur ce revêtement (402). L'émulsion de graphite (402) lie le film de graphite (406) à la plaque métallique (400) et étanchéifie les porosités (410) fines du film de graphite (406). On forme des champs de courant (414) par estampage de la plaque de pile à combustible revêtue.
