Graphene oxide (GO) has attracted a lot of attention in the field of low temperature fuel cells. Most studies have focussed on the use of GO as a support material for metal nanocatalysts. More recently use of GO in other fuel cell components, such as proton conducting membranes, is also gaining momentum. The presence of large amounts of various oxygen functional groups make it ideal for the nucleation and growth of metal nanostructures, tailoring of catalyst properties and for enhancing water uptake and retention to allow better proton conduction. 

My talk willprovide an overview of our recent studies on graphene oxide in fuel cell components. From tailoring and boosting CO tolerance of Pt supported on partially reduced GO to developing GO based composite and multi-layered membranes for Polymer Electrolyte Fuel Cells. The talk will also touch upon combining bacterial interactions of GO and precious metal reclamation for the development of catalyst-reduced GO systems.
