About the Instructors

Stuart B. Adler is an Associate Professor of Chemical Engineering at the University of Washington, Seattle. His work focuses on electrochemical ceramics, including advanced measurement and modeling techniques for solid-state electrodes, and independent studies of kinetic, transport, and thermodynamic properties of solids. Dr. Adler received his PhD in 1993 from the University of California, Berkeley. After a postdoc at Imperial College, UK, he was a staff scientist at Ceramatec, Inc. before rejoining academia in 1999. Professor Adler’s awards include a NSF-NATO postdoctoral Fellowship (1993), NSF Career Award (2001), the ECS Charles W. Tobias Young Investigator Award (2004), and the UW Junior Faculty Innovator Award (2007).

Nguyen Minh is an internationally known expert on solid oxide fuel cells (SOFCs) and related technologies. He has been involved in the development of SOFCs and new energy systems for the last 25 years. His experience covers a full spectrum of industrial/product R&D areas, ranging from technology assessment, strategy and roadmap formulation, fundamental and engineering study to processes and manufacturing development, system design and operation, prototype demonstration, and cost/market analysis.

Dr. Minh is currently Associate Director, Center for Energy Research at University of California, San Diego and an independent consultant on SOFCs. Until May 2007, he was Chief Scientist, General Electric (GE) Global Research, Torrance, CA. As the Chief Scientist, Dr. Minh was responsible for the organization’s overall technical objectives, oversaw the broad technical roadmap and R&D direction, and served as the Principal Investigator of GE multi-million dollar fuel cell programs and the primary technical representative to customers and industry. From 2001-2004, he was Manager, Fuel Cells and led the fuel cell group at GE to develop SOFCs and SOFC/gas turbine hybrid power systems for commercialization. He was responsible for group performance and provided technical direction, coordinated group activities, and assisted in business strategic planning.

Dr. Minh has been a consultant to the U.S. Department of Energy (USDOE), United Nations Industrial Development Organization (UNIDO), and a number of organizations and companies. Dr. Minh is the author/coauthor of the book “Science and Technology of Ceramic Fuel Cells” as well as five book chapters, 20 patents, and over 100 published technical articles on fuel cells and related technologies.
