Abstract
A multilayer structure, of use as composite diffusion layer in a proton-exchange membrane fuel cell, including at least one mat of carbon nanotubes having a unit diameter of less than or equal to 20 nm, defining at least one face of the structure, the mat of carbon nanotubes being superposed on a support based on carbon fibres. It also relates to a process for preparing such a multilayer structure and to the use thereof for an electrode of a PEMFC.
