This study discusses three conductive materials—carbon nanotube, graphene oxide, and montmorillonite which recently being used as fillers in membranes of fuel cell application and commonly hybridized with polymers as the matrix. The polymer electrolyte membrane fuel cell (PEMFC) is using a polymer‐based membrane as the electrolyte, which might require filler or functionalization to enhance their cell performance. This review provides brief information for the researcher who insists on improving the current PEM using these potential fillers, specified with required values of membrane properties measurement. It also entails the special features of the nanofillers concerning their chemical structure and electrochemical properties based on recent studies. As electricity is generated from an external fuel source, the membranes that are used should be more than 0.1 S/cm of proton conductivity, low fuel permeability (< 1.37 x 10⁻⁶ cm²/s), cheap, and high stability in dry and wet condition. PEM is widely being utilized together with filler(s) incorporated as a purpose to overcome recent drawbacks encountered by the commercial Nafion membrane solely. Hence, the fillers embedded in the membrane are necessarily to have the promising characteristics, acknowledging the potential performances of three conductive nanofillers of (a) carbon nanotubes which is well‐known of its electrical conducting potential with three cylindrical design, (b) graphene oxide which is a reactive carbonaceous material with its multifunctional groups and (c) montmorillonite which is one of the clay types that has tetrahedral and octahedral layers of alumina‐silicates for producing better hybrid polymer electrolyte membrane.

碳纳米管，氧化石墨烯和蒙脱石作为燃料电池聚合物电解质膜中的导电填料：概述

这项研究讨论了三种导电材料-碳纳米管，氧化石墨烯和蒙脱石，它们最近在燃料电池应用的膜中用作填充剂，并且通常与聚合物作为基质进行杂交。聚合物电解质膜燃料电池（PEMFC）使用基于聚合物的膜作为电解质，可能需要填料或功能化以增强其电池性能。这篇综述为坚持使用这些潜在的填料来改善当前PEM的研究人员提供了简要的信息，并指定了所需的膜性能测量值。基于最近的研究，这还涉及纳米填料的化学结构和电化学性能方面的特殊特征。由于电力是由外部燃料产生的，^-6 cm ² / s），便宜，在干湿条件下都具有很高的稳定性。PEM与掺入的填料一起被广泛使用，以克服仅商业上的Nafion膜遇到的最新缺点。因此，嵌入膜中的填充物必须具有令人鼓舞的特性，因为它们承认三种导电纳米填充物的潜在性能：（a）碳纳米管的导电潜能众所周知，具有三种圆柱设计，（b）氧化石墨烯它是一种具有多官能团的活性碳质材料，并且（c）蒙脱石是一种粘土类型，具有氧化铝-硅酸盐的四面体和八面体层，用于生产更好的混合聚合物电解质膜。
