Graphene, a material with exceptional properties, has dragged an attention worldwide due to its applicability in wide range of applications particularly in energy sector. With the growing human population, an intense need has aroused to explore alternate ways to meet upsurge demand of energy, where the sources of non-renewable energy are limited. Energy conversion and storage devices e.g. fuel cell, electrolyzer, batteries use polymer electrolyte membranes (PEM) as electrolyte/separator, as an important component. PEM plays a vital role in such devices, which can be prepared by functional polymers. Various PEMs consisting of various fillers have been developed to fulfill the needs of energy devices. Graphene oxide (GO), a fascinating material, has stimulated interest among researchers due to its various applications including energy based devices. This review mainly deals with graphene oxide (GO) based polymer electrolyte membranes and their applications in energy devices. Advancements in the development of GO membranes, interaction with polymer matrix and their electrochemical properties has been summarized. This review provides a profound insight about graphene based polymer electrolyte membranes for energy related applications including polymer electrolyte membranes fuel cell (PEMFC), vanadium redox flow battery (VRB) and Li-ion battery.
