A well-recognised prospective material for developing fuel cell technology is graphene, which is a two-dimensional carbon allotrope with remarkable characteristics. Unlike different conventional materials, its unmatched characteristics, such as high electrical conductivity, wide surface area, and superior mechanical strength, offer substantial benefits. In this chapter, the performance of different fuel cells based on graphene materials has been presented. Graphene-based materials can improve the efficiency of hydrogen fuel cells and direct methanol fuel cells (DMFCs) in proton exchange membrane fuel cells (PEMFCs). Graphene-based catalysts can result in thriving power densities and longer lives by enhancing mass transfer, stability, and catalytic activity. Graphene-based cathode materials can ease effective oxygen reduction processes in solid oxide fuel cells (SOFCs), improving overall cell performance and lowering operating temperatures. Furthermore, by facilitating the creation of more effective, long-lasting, and reasonably valued systems, graphene-based catalysts have the potential to dynamically transform fuel cell technology. As investigations into the potential of graphene in fuel cells persist, breakthroughs in renewable energy technology can be predicted.
