Abstract
(EN)
Poly(aryl alkylene) polymers or poly(aryl-crown ether-alkylene) polymers with pendant cationic groups are provided which have an alkaline-stable cation, such as imidazolium, introduced into a rigid aromatic polymer backbone free of ether bonds. Hydroxide exchange membranes or hydroxide exchange ionomers formed from these polymers exhibit superior chemical stability, hydroxide conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties in an ambient dry state as compared to conventional hydroxide exchange membranes or ionomers. Hydroxide exchange membrane fuel cells and hydroxide exchange membrane electrolyzers comprising the poly(aryl aikylene) polymers or poly(aryl-crown ether-alkylene) polymers with pendant cationic groups exhibit enhanced performance and durability at relatively high temperatures.
(FR)
La présente invention concerne des polymères de poly(aryl alkylène) ou des polymères de poly(aryl-couronne éther-alkylène) ayant des groupes cationiques pendants qui présentent un cation stable en milieu alcalin, tel que l'imidazolium, introduit dans un squelette polymère aromatique rigide dépourvu de liaisons éther. Des membranes d'échange d'hydroxyde ou des ionomères d'échange d'hydroxyde formés à partir de ces polymères présentent une stabilité chimique supérieure, une conductivité d'hydroxyde supérieure, une absorption d'eau réduite, une bonne solubilité dans des solvants sélectionnés, et des propriétés mécaniques améliorées dans un état sec ambiant par rapport aux membranes ou ionomères d'échange d'hydroxyde classiques. Les piles à combustible à membrane d'échange d'hydroxyde qui comprennent les polymères de poly(aryl alkylène) ou des polymères de poly(aryl-couronne éther-alkylène) ayant des groupes cationiques pendants présentent des performances et une durabilité améliorées à des températures relativement élevées.
