Anionic Exchange Membranes (AEM) Water Electrolizers (WE) are gaining strong interest due to the possibility to exploit of PGM-free catalysts, attaining a reduction of capital-costs associated with green hydrogen production. The main limitation to the development of these devices is the poor stability of AEM in alkaline environment. Poly(aryl piperidinium) (PAPs) AEMs have an heteroatom-free aromatic backbone and piperidinium cationic group which allows a good alkali resistance.

Abstract
Anionic Exchange Membranes (AEM) Water Electrolizers (WE) are gaining strong interest due to the possibility to exploit of PGM-free catalysts, attaining a reduction of capital-costs associated with green hydrogen production. The main limitation to the development of these devices is the poor stability of AEM in alkaline environment. Poly(aryl piperidinium) (PAPs) AEMs have an heteroatom-free aromatic backbone and piperidinium cationic group which allows a good alkali resistance. Here we present a work on synthesis, characterization and WE cell tests of the simplest and cheapest PAP: Poly(biphenyl piperidinium (PBP).File in questo prodotto:
