报告摘要：

One of the grandchallenges facing humanity today is the development of an alternative energysystem that is safe, clean, and sustainable and where combustion of fossilfuels no longer dominates. A distributed renewable electrochemical energy andmobility system (DREEMS) could meet this challenge. At the foundation of this newenergy system, we have chosen to study a number of electrochemical devicesincluding fuel cells, electrolyzers, and flow batteries. For all these deviceselectrocatalysis and polymer electrolytes play a critical role in controllingtheir performance, cost, and durability, and thus their economic viability. Inthis presentation, I will focus on our recent work on hydroxide exchangemembrane fuel cells (HEMFCs) which can work with nonprecious metal catalystsand inexpensive hydrocarbon polymer membranes. More specifically I will show theroadmap we have developed for this technology, the progress we have made indeveloping the most stable membranes and the most active nonprecious metalcatalysts. I will also discuss why hydrogen oxidation reactions are slower inbase than in acid for precious metal catalysts.

Yushan Yan is the Distinguished Engineering Professor and the Associate Dean for Research and Entrepreneurship of theCollege of Engineering at the University of Delaware. He studied Chemical Physics (BS) at the University of Science and Technology of China, Heterogeneous Catalysis at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, and Chemical Engineering (MS/PhD) at the California Institute of Technology. He worked for AlliedSignal as Senior Staff Engineer and Project Leader before joining the faculty at the Universityof California Riverside where he served as the Department Chair. His major recognitions include Fellow of the American Association for the Advancement of Science, the Donald Breck Award from the International Zeolite Association, the Nanoscale Science and Engineering Forum Award from the American Institute of Chemical Engineers, and the Energy Technology Division Award from the Electrochemical Society. He was one of 37 awardees of the US Department of Energy’s ARPA-E OPEN 2009 (1st open call for proposals) and one of 66 awardees of the ARPA-E OPEN 2012 (2nd open call for proposals). He has been an inventoron a number of issued or pending patents, some of which were licensed to formstartup companies (e.g., NanoH2O and OH-Energy). His research has led to 230+ publications that are widely cited (14,000+ citations, h-index = 64 and averagecitation/paper = 61) and been extensively covered by the media including New Scientist, Business Week, C&EN News,Materials Today, MRS360, Chemical Engineering Progress, China Press, ChineseDaily News, CNBC, CNN.com, KABC, Radio Australia, and VOA.
