Abstract:
The present invention relates to a gas diffusion layer for a fuel cell, made of a carbon substrate grafted with at least one aromatic group having formula (II): wherein: the asterisk * designates a carbon atom with no hydrogen and no Ri group, with i=1 to 5, and covalently bonded to the carbon substrate; at least two of the R1, R2, R3, R4, and R5 groups are different from a hydrogen atom; at least two of the R1, R2, R3, R4, and R5 groups are hydrophobic groups or hydrophilic groups or a hydrophobic group and a hydrophilic group.
