A membrane electrolyte that restricts the methanol cross-over while retaining proton conductivity is essential for better electrochemical selectivity in direct methanol fuel cells (DMFCs). Extensive research carried out to explore numerous blends and composites for application as polymer electrolyte membranes (PEMs) revealed promising electrochemical selectivity in DMFCs of carbon nanomaterial-based polymer composites. The present review covers important literature on different carbon nanomaterial-based PEMs reported during the last decade. The review emphasises the proton conductivity and methanol permeability of nanocomposite membranes with carbon nanotubes, graphene oxide and fullerene as additives, assessing critically the impact of each type of filler on those properties.
一种能限制甲醇渗透同时保持质子传导性的膜电解质对于直接甲醇燃料电池（DMFC）实现更好的电化学选择性至关重要。为探索众多用作聚合物电解质膜（PEM）的共混物和复合材料而开展的大量研究表明，基于碳纳米材料的聚合物复合材料在DMFC中具有良好的电化学选择性。本综述涵盖了过去十年间报道的关于不同基于碳纳米材料的PEM的重要文献。该综述着重介绍了以碳纳米管、氧化石墨烯和富勒烯为添加剂的纳米复合膜的质子传导性和甲醇渗透性，并严格评估了每种填料对这些性能的影响。
