The invention relates to a membrane for fuel cells, containing polymers comprising phosphonic acid groups and/or sulfonic acid groups, said membrane being characterised in that the polymer comprising phosphonic acid groups and/or sulfonic acid groups can be obtained by the copolymerisation of monomers comprising phosphonic acid and/or sulfonic acid groups, and hydrophobic monomers.
L'invention concerne une membrane destinée à des cellules électrochimiques, comportant des polymères contenant des groupes d'acide phosphonique et/ou d'acide sulfonique, caractérisée en ce que le polymère contenant des groupes d'acide phosphonique et/ou d'acide sulfonique peut être obtenu par copolymérisation de monomères contenant des groupes d'acide phosphonique et/ou d'acide sulfonique et de monomères hydrophobes.
