Patent

CA 2465654

A method is provided for making a hydrophilic carbon fiber construction, such as a fuel cell gas diffusion layer or diffuser/current collector, by electrophoretic deposition of a metal oxide selected from Type I or Type II, where Type I consists of metal oxides having a negative zeta potential and Type II consists of metal oxides having a positive zeta potential. A hydrophilic carbon fiber construction is provided, such as a fuel cell gas diffusion layer or diffuser/current collector, which is coated with a metal oxide and capable of wicking 200mg of water per 40mg of the hydrophilic carbon fiber construction.

L'invention concerne un procédé permettant de fabriquer une construction en fibre de carbone hydrophile, telle qu'une couche de diffusion gazeuse ou diffuseur/collecteur de courant de pile à combustible, par revêtement par électrophorèse d'un oxyde métallique choisi parmi les oxydes métalliques de Type I ou de Type II; les oxydes métalliques de Type I étant des oxydes métalliques présentant un potentiel zêta négatif et les oxydes métalliques de Type II étant des oxydes métalliques présentant un potentiel zêta positif. L'invention concerne une construction en fibre de carbone hydrophile, telle qu'une couche de diffusion gazeuse ou diffuseur/collecteur de courant de pile à combustible, enrobée d'un oxyde métallique et présentant une pénétration capillaire de 200 mg d'eau pour 40 mg de construction en fibre de carbone hydrophile.
