Abstract (en)
[origin: WO2017064443A1] 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.
