Thermal crosslinking of an alkaline anion exchange membrane bearing unsaturated side chains

Thermal Crosslinking of an Alkaline Anion Exchange Membrane Bearing Unsaturated Side Chains

We report a facile new route for the synthesis of self-crosslinked anion exchange membranes (AEM) without the need for any crosslinkers or catalysts. The soluble copolymers bearing flexible side chains, with alkene pendant groups, were synthesized via the Menshutkin reaction. The crosslinked derivatives were then prepared by the thermal crosslinking of the unsaturated side chains during the mem...

Ionic Copolymers for Alkaline Anion Exchange Membrane Fuel Cells (AAEMFCs)

Poly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review

Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...

An electron-beam-grafted ETFE alkaline anion-exchange membrane in metal-cation-free solid-state alkaline fuel cells

A novel, physically strong, quaternary-ammonium-functionalised radiation-grafted ETFE alkaline anion-exchange membrane (AAEM) has been developed for application in fuel cells without undesirable addition of MOH into the anode fuel stream, thereby facilitating stable performances and long term operational lifetimes. A promising H2/O2 fuel cell peak power performance of 130 mW cm -2 was obtained ...
