Novel characteristics of graphene have captured great attention of researchers for energy technology applications. Incorporation of graphene related hybrid and composite materials have demonstrated high performance and durability for fuel cell energy conversion devices. This article overviews graphene based materials for fuel cell technology applications such as electrodes additives, bipolar plates and proton conducting electrolyte membrane. The graphene dispersion over electrodes has revealed enhanced exposure of electrochemically active surface area for improved electro-catalytic activity towards fuel oxidation and oxidant reduction reactions. The issue of device stack durability and degraded performance due to corrosion of bipolar plates is discussed by incorporating graphene based materials. In proton exchange membrane devices, graphene as an electrolyte has shown an excellent performance towards high ionic conductivity and power density. The graphene incorporation in fuel cell devices has exhibited commendable performance and has bright future for commercial applications.
