Swelling shall also be minimized. The process shall also be performable with fluorine-free ionomers. The invention is based on the finding that the addition of certain organic substances has the result that the AEM swells only to a small extent, if at all (antiswelling agent). It has surprisingly been found that substances suitable as antiswelling agents are identifiable by their solubility behaviour, more particularly by their Hansen parameters.

The present invention provides a high-temperature proton exchange membrane (HT-PEM) for a fuel cell and a preparation method therefor. The HT-PEM is prepared by means of a cross-linking reaction of specific polybenzimidazole and imidazole ionic liquid. By means of the structural design of a nitrogen-containing bulky group in the polybenzimidazole and the introduction of the bulky side group-substituted imidazole ionic liquid, the free volume is improved, the phosphoric acid doping amount and the phosphoric acid retention amount are increased, and proton conduction is promoted. A cross-linked network is constructed by using the cross-linking method, so that the phosphoric acid doping amount and the retention capacity are improved while the creep resistance, mechanical properties, and swelling resistance of the membrane material are enhanced. The dependence of the membrane material on the phosphoric acid doping amount is reduced by utilizing the promoting effect of the polyionic liquid on proton conduction, so that high proton conductivity can be obtained at a low phosphoric acid doping amount; and in addition, by means of the ionic interaction between the polyionic liquid and the phosphoric acid, the interaction between phosphoric acid molecules and a system is enhanced, thereby obtaining a HT-PEM having excellent phosphoric acid retention capacity.
