Hydroxide exchange membrane fuel cells (AEMFC) are clean energy conversion devices that are an attractive alternative to the more common proton exchange membrane fuel cells (PEMFCs), because they present, among others, the advantage of not using noble metals like platinum as catalysts for the oxygen reduction reaction. The interest in this technology has increased exponentially over the recent years. Unfortunately, the low durability of anion exchange membranes (AEM) in basic conditions limits their use on a large scale. We present in this review composite AEM with one-dimensional, two-dimensional and three-dimensional fillers, an approach commonly used to enhance the fuel cell performance and stability. The most important filler types, which are discussed in this review, are carbon and titanate nanotubes, graphene and graphene oxide, layered double hydroxides, silica and zirconia nanoparticles. The functionalization of the fillers is the most important key to successful property improvement. The recent progress of mechanical properties, ionic conductivity and FC performances of composite AEM is critically reviewed.
氢氧化物交换膜燃料电池（AEMFC）是一种清洁能源转换装置，是更常见的质子交换膜燃料电池（PEMFC）的一种有吸引力的替代方案，因为它们具有诸多优点，其中包括在氧还原反应中不使用铂等贵金属作为催化剂。近年来，对这项技术的兴趣呈指数级增长。不幸的是，阴离子交换膜（AEM）在碱性条件下的低耐久性限制了它们的大规模应用。在本综述中，我们介绍了含有一维、二维和三维填料的复合AEM，这是一种常用于提高燃料电池性能和稳定性的方法。本综述中讨论的最重要的填料类型是碳和钛酸盐纳米管、石墨烯和氧化石墨烯、层状双氢氧化物、二氧化硅和氧化锆纳米颗粒。填料的功能化是成功改善性能的最重要关键。本文对复合AEM的机械性能、离子电导率和燃料电池性能的最新进展进行了批判性综述。
