Preparation and Characterization of fluoropolymer anion exchange membrane for alkaline direct methanol fuel cells

摘要

A series of hydroxyl-conducting anion-exchange membranes base on the copolymer of 2-(Diethylamino)ethyl methacrylate and fluoro-polyacrylate has been prepared, and their potential applications in alkaline fuel cells are assessed. The anionic conductivity of this kind of membrane can reach 0.0518 Scm~(-1) in deionized water at 25 °C. An open-circuit voltage of 0.71V and a maximum power density of 43.2mW cm~(-2) of alkaline direct methanol fuel cell at 65 °Care obtained. Therefore, this AEMs would have potential for applications in low-temperature fuel cell systems.
