Abstract
Radiation-grafted anion-exchange ionomer powders were tested in anion-exchange membrane fuel cells.
Highlights
Fuel cells are considered an efficient and clean energy conversion technology, which can offer superior energy efficiencies to conventional technologies, such as combustion engines
This study involved the development of ETFE-based radiationgra ed anion-exchange ionomer (AEI) powders containing different head-group chemistries made using trimethylamine (TMA), N-methylpyrrolidine (MPY), and N-methylpiperidine (MPRD) amination agents
The resulting anion-exchange membrane fuel cell (AEMFC) performance tests on these membrane-electrode assembly (MEA) showed that all the head-group chemistries yielded excellent AEMFC performances at 60 C
Summary
Fuel cells are considered an efficient and clean energy conversion technology, which can offer superior energy efficiencies to conventional technologies, such as combustion engines. Such devices have been considered promising, due to the ability to directly convert chemical energy (provided from a fuel, e.g. H2) into electrical energy, with wide applicability in mobile (transportation), portable, and stationary systems.[1,2]. The main cause of degradation of various anion conducting groups and polymer chains is the alkalinity of the medium (high pH), a problem that is especially severe in materials containing lower hydration levels.[7,8] AEMs are formed
