摘要： The invention relates to a fabric comprising carbon threads, said fabric having a mass per unit area in the range from 40 g/m2 to 100 g/m2, preferably in the range from 40 g/m2 to 80 g/m2, particularly in the range from 60 g/m2 to 80 g/m2, and characterised in that it comprises discontinuous fibres, said discontinuous fibres extending from threads constituting the fabric from which they come and extending non-parallel to the direction of the thread from which they come and/or in that the fabric is needled. The invention also relates to the use of said fabric in a diffusion layer for a fuel cell and a method for producing said diffusion layer.

摘要： La présente invention concerne un procédé de traitement d'un substrat en carbone, comprenant les étapes suivantes et successives :
- imprégnation du substrat en carbone avec une solution aqueuse contenant un copolymère fluoré amorphe de tétrafluoroéthène et de perfluorométhoxy dioxole ;
- séchage du substrat en carbone à une pression inférieure à la pression atmosphérique ;
- obtention d'un substrat en carbone imprégné d'un copolymère fluoré.
Ce substrat en carbone peut être utilisé en tant que couche de diffusion gazeuse dans une pile à combustible.摘要翻译： 本发明涉及一种处理碳基材，所述方法包括以下连续步骤的方法： - 浸渍用含有四氟乙烯和全氟甲氧基间二氧杂环戊的无定形含氟共聚物的水溶液中的碳基材; 在低于大气压的压力下干燥碳基底; 获得浸渍有含氟共聚物的碳基材。 该碳基板可以用作燃料电池中的气体扩散层。
