Advances in Solid Oxide Fuel Cells A

Due to its many potential benefits, including high electrical efficiency and low environmental emissions, solid oxide fuel cell (SOFC) technology is the subject of extensive research and development efforts by national laboratories, universities, and private industries. This collection of papers provides valuable insights on materials-related aspects of fuel cells such as SOFC component materials, materials processing, and cell/stack design, performance, and stability. Emerging trends in electrochemical materials, electrodics, interface engineering, long-term chemical interactions are also covered.

Narottam P. Bansal, PhD, is Senior Research Scientist at the NASA Glenn Research Center, where he has conducted research on glasses, ceramics, and composites since 1985. In addition to publishing more than 230 papers, Dr. Bansal holds seven patents and is the author or editor of five books and 32 conference proceedings.

Dongming Zhu received his Ph.D. degree in Chemical Engineering and Materials Science from the University of Minnesota in 1996 and is a senior Materials Research Engineer at Army Research Laboratory at NASA Glenn Research Center. He has authored more than 100 archival publications and three patents. He is a member of the American Ceramic Society and ASM, International, has been a lead organizer for several International Symposia. He is currently the Chair-elect of the Engineering Ceramic Division of the American Ceramic Society, and an associate editor of the International Journal of Applied Ceramic Technology.
