Due to a significant increase in the demand for usable power, research focused on energy-material relations has garnered considerable attention. Fuel cells, characterized by their high efficiency, high energy density, quiet operation, and environmental friendliness, are regarded as a promising future power source that provides clean power at the point of use. The incorporation of functionalized graphene quantum dots (GQDs) has been shown to enhance catalytic activity and stability, making them attractive materials for various device applications, particularly in fuel cells. This review presents an overview of different synthesis methods for GQDs and discusses the utilization of GQD-doped composites with optimized content and enhanced electro conductivity as electrocatalysts in fuel cells.
