报告简介:
Two of the major challenges for development of polymer electrolyte membrane fuel cell (PEMFC) systems, especially for automotive applications, are cost and durability of the precious metal group (PGM) based cathode electrocatalysts. High performance and durable membrane electrode assembly (MEA) using the Pt/3-D Graphene catalyst was developed focusing our bottom up approach—from catalyst ink to the structure of the solid catalyst layer in MEA. We have developed a methodology to study the catalyst powder and Nafion ionomer dispersion in the catalyst ink using small angle x-ray scattering (USAXS) combined with cryogenic TEM, etc. The property-structure-performance relationship was established and is promising for application in fuel cell vehicles (FCVs).

报告人简介:
Dr. Xie is a professor of Mechanical and Energy Engineering at the Purdue School of Engineering and Technology, IUPUI. He has published more than 55 journal papers (including Nature.Energy (IF46.87), Nature.Comm, Chem, NanoEnergy, etc.) and 2 book chapters, has 11 US patent applications (6 issued), and has been awarded more than USD 5.86 million in research grants within 10 years. He serves as a panelist reviewer for the US National Science Foundation, and the US Department of Energy Office of Technology Transfer. Before joining the university, he conducted research at Los Alamos National Laboratory (LANL) and General Motors (GE) for fuel cells, Li-ion batteries in Electric Vehicles (EVs) and Hybrid EVs. He received his PhD in chemistry from Miami University, and a BS in chemical engineering from Tianjin University, China.
