Title (EN) POLY(ARYL PIPERIDINIUM) POLYMERS INCLUDING THOSE WITH STABLE CATIONIC PENDANT GROUPS FOR USE AS ANION EXCHANGE MEMBRANES AND IONOMERS
(FR) POLYMÈRES DE POLY(ARYL PIPÉRIDINIUM) COMPRENANT CEUX AYANT DES GROUPES PENDANTS CATIONIQUES STABLES POUR UNE UTILISATION EN TANT QUE MEMBRANES ÉCHANGEUSES D'ANIONS ET IONOMÈRES
Abstract:
(EN) Poly(aryl piperidinium) polymers with pendant cationic groups are provided which have an alkaline-stable cation, piperidinium, 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 comprising the poly(aryl piperidinium) polymers with pendant cationic groups exhibit enhanced performance and durability at relatively high temperatures.
(FR) La présente invention concerne des polymères de poly(aryl pipéridinium) à groupes cationiques pendants qui présentent un cation stable en milieu alcalin, le pipéridinium, 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 pipéridinium) à groupes cationiques pendants présentent des performances et une durabilité améliorées à des températures relativement élevées.
