Dr. Wei Xing is a Professor and Dean at the Advanced Chemical Power Sources, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (CIAC-CAS). Prof. Xing received his PhD in Electrochemistry from CIAC-CAS in 1987, since then, as one of the key senior researchers, he established, and continues to lead the Laboratory of Advanced Power Sources at CIAC-CAS, that develops novel proton exchange membrane fuel cells (PEMFC) catalysts and technologies. His research is mainly concentrated on the R&D of fuel cell technologies including PEMFCs, direct methanol fuel cells (DMFCs), direct formic acid fuel cells (DFAFCs), in which cathode catalyst development for oxygen reduction reaction is the major focus. To date, he has published more than 160 referred journal papers, 3 books, 39 patents. Dr. Xing’s research and scientific contributions are internationally recognized. Dr. Geping Yin is a Professor and Vice Dean at the School of Chemical Engineering and Technology, and Director at the Centre for Chemical Power Sources, Harbin Institute of Technology. Dr. Yin received her B.S. in Electrochemistry in 1982 and her Ph.D. in Environmental Science in 1988 from Harbin Institute of Technology, respectively. She has more than 30 years of experience in electrochemistry and over 20 years of R&D activity in fuel cells and electrocatalysis. Dr. Yin is internationally renowned in electrochemistry and is distinguished for her contributions to fuel cell catalysis. She has published more than 180 papers in prestigious journals with over 2800 citations, 3 edited books, and 60 conference proceeding papers. She also holds over 20 patents and 6 patent pending in the area of electrochemistry and electrocatalysis. Dr. Jiujun Zhang is a Senior Research Officer and Catalysis Core Competency Leader at the National Research Council of Canada Institute for Fuel Cell Innovation (NRC-IFCI, now changed to Energy, Mining & Environment Portfolio (NRC-EME)). Dr. Zhang received his B.S. and M.Sc. in Electrochemistry from Peking University in 1982 and 1985, respectively, and his Ph.D. in Electrochemistry from Wuhan University in 1988. After completing his Ph.D., he took a position as an associate professor at the Huazhong Normal University for two years. Starting in 1990, he carried out three terms of postdoctoral research at the California Institute of Technology, York University, and the University of British Columbia. Dr. Zhang has over 30 years of R&D experience in theoretical and applied electrochemistry, including over fourteen years of fuel cell R&D (among these 6 years at Ballard Power Systems and 9 years at NRC-IFCI), and 3 years of electrochemical sensor experience. Dr. Zhang holds several adjunct professorships, including one at the University of Waterloo, one at the University of British Columbia and one at Peking University. Up to now, Dr. Zhang has co-authored 290 publications including 190 refereed journal papers with more than 5000 citations, 9 edited /co-authored books, 11 conferences proceeding papers, 12 book chapters, as well as 50 conference and invited oral presentations. He also holds over 10 US/EU/WO/JP/CA patents, 9 US patent publications, and produced in excess of eighty industrial technical reports. Dr. Zhang serves as the editor /editorial board member for several international journals as well as Chief-in-Editor for book series (Electrochemical Energy Storage and Conversion, CRC press). Dr. Zhang is an active member of The Electrochemical Society, the International Society of Electrochemistry, and the American Chemical Society.
