Novel Anion Exchange Membranes Base on Copolymer of 2-(Diethylamino) Ethyl Methacrylate and Fluoro-Polyacrylate for Alkaline Direct Methanol Fuel Cells
摘要
Abstract
Anion exchange membrane fuel cells,which use anion exchange membranes as polyelectrolytes, have attracted more and more research interests recently. In this work, a series of hydroxyl-conducting anion-exchange membranes based on the copolymer of 2-(Diethylamino) ethyl methacrylate and fiuoro-polyacrylate were prepared by radical polymerization, and their potential applications in alkaline fuel cells were assessed. It was shown that the ionic conductivity of the membranes reached 10-2 S ·cm- 1 at room temperature, while the methanol permeability was lower than 10-7 cm2 · s-1. The maximum power density of fuel cell assembled with this membrane was achieved to be 43.2 mW ·cm -2 at room temperature, indicating possible application of this membrane in alkaline fuel cells.关键词
