报告内容摘要：
The transport phenomena involved in a polymer electrolyte membrane fuel cell (PEMFC) are complex and strongly coupled. These phenomena take place over a wide range of length scale, from nanometers of the catalyst to meters of a system. Models on PEMFCs in the past decade have been mostly developed following the divide-and-conquer strategy, namely, focusing on the components of a membrane electrode assembly (MEA) - including the membrane, catalyst layer, microporous layer/gas diffusion layer, or beyond the MEA – including bipolar plate and fluid channels, stack and fuel cell system. Computational methods such as CFD, lattice Boltzmann method, pore-scale model, molecular dynamics have been employed to study certain transport phenomena for some components, yet a holistic approach to deal with the multiscale, multiphase and multicomponent problem in PEMFC is lacking. In this talk an overview on the current status of modeling and simulation for PEMFC will be given, followed by discussion on the roadmap for a systematic development of a truly multiscale simulation.
报告人简介：
Dr. Pang-Chieh (Jay) Sui received his Ph.D. degree in Mechanical Engineering from The University of Iowa, Iowa City, U.S.A, in 1997. He then worked as a Research Scientist in the National Driving Simulator at University of Iowa as well as Adjunct Assistant Professor in the Mechanical Engineering Department there during 1997-2003. He joined the Institute for Integrated Energy Systems (IESVic) in University of Victoria, Canada, in 2003. He is currently Senior Research Engineer in IESVic and Manager of the Energy Systems and Transport Phenomena Lab. Dr. Sui’s research interests include Polymer Electrolyte Membrane Fuel Cells (PEMFCs), Combustion and Flame, Transport Phenomena at Near-critical States, Multiscale Simulations, Laser Diagnostics for flame, sprays and turbulent flows, etc. He is a member of ASME and AIChE and constantly attends conferences of both societies to chair sessions. He served as the Vice Chair of the ISTP-20 conference in 2009. He has been involved in several collaborative activities with research organizations in the U.S., Canada, and China & Taiwan. His other educational degrees and past employment include a BS from Power Mechanical Engineering in 1986 from National Tsing Hua University, 1986-88 Artillery Second Lieutenant, 1990-92 Assistant Researcher in Industrial Technology Research Institute in Taiwan, and 1992 MS degree in Mechanical Engineering from University of Iowa.
