Graphene-Based Fuel Cells

Graphene has received much attention in energy conversion devices due to its remarkable properties such as unique thermal, mechanical, electronic, and chemical properties. Also, graphene has an isolated layer of carbon hexagons with Sp2 hybridized C–C bonds with electron clouds. Thin flakes made of a few layers of carbon atoms, such as mono-layer graphene, can be very significant from an engineering perspective due to their intriguing structural and physical properties as well as their potential for exciting technology applications. Hybrid structures based on graphene have been used to create a wide range of effective and long-lasting fuel cell energy systems. Graphene in fuel cell technology exhibits excellent catalytic performance in potential applications of fuel cell devices. This chapter focuses on the fuel cell device used by graphene and how graphene is used in contemporary fuel cell technology, including in electrodes.
