One of the most important challenges for the ultimate commercialization of fuel cells is the preparation of active, robust, and low-cost electrocatalysts. In particular, better electrocatalysts for the fuel cell cathode, where oxygen reduction reaction (ORR) requiring a high overpotential occurs, are needed to improve the efficiency and to lower the cost of fuel cells. In this respect, various nanostructured materials are of interest and have been studied for their catalytic activities. Since graphene was first discovered, it has been studied extensively and received great attention by scientists because of its low cost and advantageous characteristics over graphite, such as high electron mobility and intensity. Furthermore, it has large specific surface area. In this presentation, graphene coated with Pd nanoparticles is synthesized via self-assembly and characterized as fuel cell cathode catalyst. The structure, morphology and electrocatalytic activity of this product is characterized by scanning electron microscopy (SEM) and rotating disk electrode (RDE). This research was supported by Mid-career Researcher Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology
