<br/>The studies of the electrochemical reaction on well-defined surfaces have guided the approach to design of the real world nanostructured materials that employed in fuel cells and batteries. Insights from single crystalline systems and thin film surfaces have yielded atomically precise information about surface structure and alloying with other metals in the quest to improve their intrinsic performance. These experimental efforts are also producing information necessary for the design of materials with enhancing stability. These accomplishments were achieved lately through electrochemical in situ ICP-MS evaluations. Atomic level insight, has guided the chemical synthesis of well-defined nanoscale surfaces and creation of novel architectures that are associated with advanced catalytic performance. The progress in platinum-transition metal alloy nanocatalysts will be in focus of this lecture, with the goal of improving the activity and durability of the oxygen reduction electrocatalyst in a proton exchange membrane fuel cell. The meticulous characterization of nanocatalysts using extremely high-purity conditions and cutting-edge techniques provides greater understanding of their performance and degradation pathways. This knowledge allows better implementation of electrocatalysts in membrane electrode assemblies (MEA) for demonstration of expected performance in a fuel cell vehicle. More recent research directions, such as platinum group metal (PGM) free catalysts will also be discussed.  Novel approach in the design of materials for advanced battery systems will be presented in terms of synergy in hybrid vehicles. <br/>
