Research Progress of Anion Exchange Membranes for Fuel Cells

碱性阴离子交换膜燃料电池(AEMFC)是一种以碱性阴离子交换膜为电解质的新型燃料电池。结合了质子交换膜燃料电池(PEMFC)和传统碱性燃料电池(AFC)的优点,从根本上摆脱了对贵金属催化剂的依赖,具有广阔的应用前景。阴离子交换膜是阴离子交换膜燃料电池的核心材料之一,其电导率及稳定性制约了碱性阴离子交换膜(AEM)的发展。从提高AEM的电导率及耐碱稳定性两个方面,对近期报道的研究工作进行梳理总结。

Alkaline anion exchange membrane fuel cell （AEMFC） is a new kind of fuel cell with alkaline anion exchange membrane as electrolyte. It combines the advantages of the proton exchange membrane fuel cell （PEMFC） and the traditional alkaline fuel cell （AFC）. Fundamentally free from dependence on noble metal catalysts. AEMFC has broad application prospects in fuel cells. The anion exchange membrane （AEM） is one of the key materials in AEMFC, the development of the AEMFC is restricted by its low conductivity and stability. The development of improving of the conductivity and alkaline stability of AEM is summarized.
