报告摘要：
With the increasing demand for energy all over the world, the quality of human life depends to a large degree on the availability of energy resources. In order to remedy the depletion of fossil fuels and their environmental misdeeds, hydrogen has been considered as an energy carrier of the future that provides a solution to the energy needs for reducing pollution and greenhouse gas emissions, and for providing fuel for fuel cells. However, hydrogen is not an energy source, and it does not typically exist by itself in nature in its elemental or molecular form. Therefore, hydrogen must be produced.
Various methods have been developed for producing hydrogen from different sources, such as fossil fuels, nuclear, biomass and renewable energy (solar, wind, geothermal and others). An overview of several projects related to hydrogen production at University of Nevada, Las Vegas will be first presented. Some obtained results for photo-electrochemical cells and improved design of electrolyzers will be shown and discussed.

Yitung Chen 教授：
Dr. Yitung Chen is Professor of the Department of Mechanical Engineering and Co-Director of the Center for Energy Research (CER) at the University of Nevada, Las Vegas (UNLV). He received his Ph.D. in Mechanical Engineering from the University of Utah in 1991. He also holds B.S. degree from Chemical Engineering and minor in Nuclear Engineering. He has published nearly 50 technical journals and 450 peer-review conference papers and 250 technical presentations in different fields that include computational fluid dynamics and numerical heat and mass transfer, finite element, finite volume, and meshless numerical techniques, lattice Boltzmann method, perturbation method, compressible flow simulation, atmospheric and environmental modeling, groundwater flow, thermal system design, renewable energy, energy conversion, data acquisition system, advance nuclear fuel cycle, fuel cell design, high temperature heat exchanger and decomposer design, corrosion modeling, hydrogen production using solar or nuclear energy, and biomedical engineering. He is the co-author of one book – “Computational Partial Differential Equations using MATLAB,” which was recently published in December 2008. He currently severs as the elected vice-president for the Chinese in America Thermal Engineering Association (CATEA).
Jianhu Nie 博士：
Dr. Jianhu Nie is Research Assistant Professor in Department of Mechanical Engineering at University of Nevada, Las Vegas. He received his B.S. degree in Mechanical Engineering in 1995 from University of Petroleum, and his Ph.D. degree in Engineering Thermophysics in 2000 from Xi’an Jiaotong University. From 2000 to 2005, he was a research scholar and Postdoctoral Fellow in Department of Mechanical and Aerospace Engineering and Engineering Mechanics at the University of Missouri-Rolla (UMR). His research interests are design of thermal systems, computational fluid dynamics and flow measurements. Dr. Nie has actively worked on the research projects funded by NSF, DOE, DOD, NASA and private sectors. His work experiences have resulted in more than two dozen peer review journal papers and over 30 proceeding publications. He served as a symposium co-organizer, session chair and co-chair at several ASME conferences and meetings.
