Zusammenfassung:	A method is provided for making a hydrophilic carbon fiber construction comprising the steps of: a) immersing a carbon fiber construction in an aqueous dispersion of one or more metal oxides, comprising: i) 1-15 % by weight metal oxide; ii) 0.01 %-5 % by weight dispersant; and b) subsequently heating the carbon fiber construction sufficiently to remove substantially all of the dispersant. Typically the entire method can be completed in less than 20 minutes. In addition, a hydrophilic carbon fiber construction made according to the method of the present invention is provided, typically having a loading of metal oxide equivalent to 20-50 mg metal per gram of carbon. L'invention concerne un procédé de production d'une construction hydrophile en fibre de carbone, qui comprend les étapes consistant: a) à immerger une construction en fibre de carbone dans une dispersion aqueuse comportant un ou plusieurs oxydes métalliques qui contient: i) entre 1 et 15 % en poids d'un oxyde métallique; ii) entre 0,01 et 5 % en poids d'un produit dispersant; et b) à chauffer ensuite la construction en fibre de carbone suffisamment pour éliminer sensiblement la totalité du produit dispersant. En général, le procédé dans son ensemble peut être effectué en moins de 20 minutes. En outre, l'invention concerne une construction hydrophile en fibre de carbone obtenue selon le procédé de l'invention, présentant en général une charge d'oxyde métallique comprise entre 20 et 50 mg de métal par gramme de carbone.
