COUCHE DE DIFFUSION GAZEUSE POUR PILE A COMBUSTIBLE, CONSTITUEE PAR UN SUBSTRAT EN CARBONE GREFFE AVEC UN GROUPEMENT AROMATIQUE
摘要:
The present invention relates to a fuel cell gas diffusion layer made up of a carbon substrate grafted with at least one aromatic grouping having Formula (II): , wherein: - the asterisk * denotes a carbon atom that is free of both hydrogen and a grouping R
i , where i = 1 through 5, and covalently bonds with the carbon substrate; - at least two of the groupings R
1 , R
2 , R
3 , R
4 , and R
5 are different from a hydrogen atom; and - at least two of the groupings R
1 , R
2 , R
3 , R
4 and R
5 are hydrophobic groupings, hydrophilic groupings, or a hydrophobic grouping and hydrophilic grouping.
