摘要
燃料电池具有能量密度大、转化率高、操作温度低、环境友好等优点,有望成为新能源技术中最具应用前景的绿色能源之一.燃料电池用阴离子交换膜具有分隔燃料与氧化剂并传导OH-的功能,是碱性燃料电池的关键部件.阴离子交换膜在近几十年迅速发展,但仍处于初始阶段,普遍存在离子电导率低的问题.本文总结了影响阴离子交换膜离子电导率的因素,重点介绍优化离子电导率的结构调控,分析了微相分离结构与离子电导率的关系,最后提出在研究过程出现的问题.
Fuel cells can be considered as one of the most potential green power due to their high power density,high energy efficiency,low operation temperature,environmental friendliness etc.As a key component of alkaline fuel cells,anion exchange membranes（AEMs）take the function of separating fuels and oxidant and transporting the hydroxide ion from the cathode to the anode.AEMs were developed rapidly in the recent several decades,but still at an outset stage.The critical issue associated with AEMs is insufficient ionic conductivity under alkaline conditions.In this paper,the influence factors on the ionic conductivity of AEMs were summarized.Some research progresses on the structure control for optimizing the ionic conductivity were described and the relationship between microphase separation and ionic conductivity were also analyzed.Finally,the problems existed in the present research and the new trend in the future were pointed out.
