Graphene Oxide-Based Hybrid Composite Films for Fuel Cell Applications
摘要
Recent research around energy is directed primarily towards fuel cells, and graphene-assisted materials have been found to increase efficiency by leaps and bounds in real-world applications. This paper discusses recent developments in graphene-based cathode materials and how this is revolutionizing the pace of fuel cell technology. Graphene is put forward as an extremely promising material to be included in solid oxide fuel cells (SOFCs) and proton-exchange membrane fuel cells (PEMFCs) due to its large surface area, better electrical conductivity, and greater mechanical stability. This paper describes in detail the various forms of graphene, including graphene oxide (GO), reduced graphene oxide (rGO), and doped graphene. It highlights their unique properties and how good they are as catalysts. Apart from this, we discuss how doping, structural modification, and functional group introduction influence the stability and electrochemical behavior of graphene-based cathodes. This study highlights the key challenge of ensuring the thermal stability of graphene derivatives in high-temperature SOFCs and discusses ways of enhancing their longevity. This paper discusses recent advancements as well as present issues to highlight the promising potential of graphene-based materials in fuel cells. These advancements can lead to more efficient, cost-saving, and long-duration energy solutions.
