Abstract

The development of alkaline anion exchange membranes (AEM) has allowed for a myriad of new liquid fuels to be used in fuel cell applications that cannot be effectively oxidized under acidic conditions using proton exchange membrane fuel cells (PEMFCs). Moreover, many of these fuels are readily electrooxidized by non-platinum group metal catalysts under basic conditions. Interested in the direct formate fuel cell (DFFC), we have explored the activity of palladium supported on reduced graphene oxide (Pd/rGO) toward the formate oxidation reaction in the alkaline medium. The reduction of GO to rGO and synthesis of Pd nanoparticles were confirmed using X-ray diffraction, Raman, and X-ray photoele..
