High-temperature proton exchange membrane, preparation method and use thereof

Abstract

Disclosed are a high-temperature proton exchange membrane, a preparation method and use thereof. The preparation method includes: mixing 1-methylimidazole with 3-chloropropyltriethoxysilane, conducting a reaction to obtain 1-methyl-3-[(triethoxysilyl)propyl]imidazole chloride; mixing the 1-methyl-3-[(triethoxysilyl)propyl]imidazole chloride with a suspension of titanium dioxide, and subjecting a resulting mixture to modification to obtain a modified titanium dioxide; and mixing the modified titanium dioxide, a polybenzimidazole powder and a solvent, and casting an obtained mixture on a substrate to obtain the high-temperature proton exchange membrane.
