LEPMI, Laboratoire d'Electrochimie et de Physicochimie des Matériaux et des Interfaces, UMR 5631 CNRS-INPG-UJF, BP 75, 38402 Saint-Martin-d'Hères Cedex, France This paper is a review that is focused on ionomers based on aromatic polysulfone backbone and intended to be used in proton exchange membrane fuel cells or in direct methanol fuel cells. Emphasis is placed on the different chemical routes to prepare the ionomers. Special attention is given to the impact of the ionomer structure on the conductivity performance and on the dimensional stability of the membranes at high temperatures.
