本文和相关的介绍将介绍有关碱性阴离子交换膜（AAEM）燃料电池在萨里的最新发展。所进行的工作计划的目标是含碱性离聚物的膜和电极的材料开发，因此重点是H-2/O-2燃料电池测试。辐射接枝的AAEM可以制成具有18 - 80 μ m之间的完全水合厚度，在60 ℃下在水中的电导率高达0.06S cm（-2）。用18 μ m的AAEM和Toray碳纸基电极制成的H2/O2燃料电池在50 ℃下获得了230 mW cm（geo）（-2）的峰值功率密度和1.3 A cm（geo）（-2）的全放电最大电流密度（Pt/C（20%质量），0.5 mg（pt）cm（geo）（-2）负载），用萨里第一代碱性离聚物处理。未来的优先事项是开发下一代碱性离聚物。
This paper and the associated presentation will describe the latest developments regarding alkaline anion exchange membrane (AAEM) fuel cells at Surrey. The program of work conducted has been targeted at the materials development of both membranes and electrodes containing alkaline ionomers and as such has focused on H-2/O-2 fuel cell testing. Radiation-grafted AAEMs can be made with fully hydrated thicknesses between 18 - 80 mu m with conductivities in water of up to 0.06 S cm(-2) at 60 degrees C. A peak power density of 230 mW cm(geo)(-2) and a maximum current density at full discharge of 1.3 A cm(geo)(-2) have been obtained in a H-2/O-2 fuel cell at 50 degrees C with a 18 mu m AAEM and Toray carbon paper based electrodes (Pt/C(20%mass), 0.5 mg(pt) cm(geo)(-2) loading) that were treated with Surrey's first generation alkaline ionomer. A future priority is the development of the next generation alkaline ionomer.
