Description

For full market implementation of PEM fuel cells to become a reality, two main limiting technical issues must be overcome-cost and durability. This cutting-edge volume directly addresses the state-of-the-art advances in durability within every fuel cell stack component. Designed to be relevant to the professional community in addition to researchers, this book will serve as a valuable reference featuring topics covered nowhere else and a one-stop-shop to create a solid platform for understanding this important area of development. The reference covers aspects of durability in the entire fuel cell stack. Each chapter also includes vision of pathways forward and an explanation of the tools needed to continue along the path toward commercialization.

Key Features

  • Features expert insights from contributing authors who are key industrial and academic leaders in the field
  • Includes coverage of two key topics in the field- Testing and Protocol for Durability, and Computational Modeling Aspects of PEFC Durability- which are newly emerging, pivotally important subjects not systematically covered anywhere else
  • Undertakes aspects of durability across the entire fuel stack, from membranes to bipolar plates

Readership

Engineers and Researchers in the Fuel Cell Industry, including Energy, Chemical, Mechanical, and Electrical Engineers, and Materials Scientists working on Fuel Cell applications in the Power, Consumer Electronics, Military, Aerospace, and Automotive sectors; Government Policy Makers; Engineering Students

T. Nejat Veziroglu

Dr. Veziroglu, a native of Turkey, graduated from the City and Guilds College, the Imperial College of Science and Technology, University of London, with degrees in Mechanical Engineering (A.C.G.I., B.Sc.), Advanced Studies in Engineering (D.I.C.) and Heat Transfer (Ph.D.).

In 1962 – after doing his military service in the Ordnance Section, serving in some Turkish government agencies and heading a private company – Dr. Veziroglu joined the University of Miami Engineering Faculty. In 1965, he became the Director of Graduate Studies and initiated the first Ph.D. Program in the School of Engineering and Architecture. He served as Chairman of the Department of Mechanical Engineering 1971 through 1975, in 1973 established the Clean Energy Research Institute, and was the Associate Dean for Research 1975 through 1979. He took a three years Leave of Absence (2004 through 2007) and founded UNIDO-ICHET (United Nations Industrial Development Organization – International Centre for Hydrogen Energy Technologies) in Istanbul, Turkey. On 15 May 2009, he attained the status of Professor Emeritus at the University of Miami.

Dr. Veziroglu organized the first major conference on Hydrogen Energy: The Hydrogen Economy Miami Energy (THEME) Conference, Miami Beach, 18-20 March 1974. At the opening of this conference, Dr. Veziroglu proposed the Hydrogen Energy System as a permanent solution for the depletion of the fossil fuels and the environmental problems caused by their utilization. Soon after, the International Association for Hydrogen Energy (IAHE) was established, and Dr. Veziroglu was elected president. As President of IAHE, in 1976 he initiated the biennial World Hydrogen Energy Conferences (WHECs), and in 2005 the biennial World Hydrogen Technologies Conventions (WHTCs).

In 1976, Dr. Veziroglu started publication of the International Journal of Hydrogen Energy (IJHE) as its Founding Editor-in-Chief, in order to publish and disseminate Hydrogen Energy related research and development results from around the world. IJHE has continuously grew; now it publishes twenty-four issues a year. He has published some 350 papers and scientific reports, edited 160 volumes of books and proceedings, and has co-authored the book “Solar Hydrogen Energy: The Power to Save the Earth”.

Dr. Veziroglu has memberships in eighteen scientific organizations, has been elected to the Grade of Fellow in the British Institution of Mechanical Engineers, American Society of Mechanical Engineers and the American Association for the Advancement of Science, and is the Founding President of the International Association for Hydrogen Energy.

Dr. Veziroglu has been the recipient of several international awards. He was presented the Turkish Presidential Science Award in 1974, made an Honorary Professor in Xian Jiaotong University of China in 1981, awarded the I. V. Kurchatov Medal by the Kurchatov Institute of Atomic Energy of U.S.S.R. in 1982, the Energy for Mankind Award by the Global Energy Society in 1986, and elected to the Argentinean Academy of Sciences in 1988. In 2000, he was nominated for Nobel Prize in Economics, for conceiving the Hydrogen Economy and striving towards its establishment.
