Description

Clean energy technologies are poised to play an important role in overcoming fossil fuel exhaustion and global pollution. Among these technologies, electrochemical energy storage and conversion are considered to be the most feasible, sustainable, and environmentally friendly. Proton exchange membrane (PEM) fuel cells are prime examples of electrochemical energy conversion technologies in action. Believed to be ideal sources of clean power, PEM fuel cells are replacing internal combustion and diesel engines in vehicles, as well as Pb-acid batteries and diesel generators in the emergency backup of telecommunications base stations and computer centers.

Written by an industry-leading scientist, Proton Exchange Membrane Fuel Cells explains the theoretical foundations of PEM fuel cells in relation to practical design and operation to not only help beginners grasp the essentials, but also guide industry professionals in tackling technical challenges. Useful to scientists, researchers, students, academics, and practicing engineers, the book covers the fundamentals, materials, components, modules, system architecture, applications, and current developmental status; offers real-world examples; and provides insight into advancing this sustainable clean technology.

Reviews

"This book covers the essentials of theory, with a focus on providing tools and techniques engineers can use during the design process. This is a balance that can only be achieved by the author’s extensive industry experience and credentials."

––Chuck Carlstrom, R & D Director, Lydall, Manchester, Connecticut, USA; Former Director of Stack Development at Plug Power, Latham, New York, USA

"This book is written by a scientist with broad knowledge of PEM fuel cells, ranging from the fundamental chemistry to commercial development and applications. …Its unique insider’s perspective displays an intimate knowledge of PEM fuel cell systems, testing methods, and commercial requirements."

––Professor Peter G. Pickup, Department of Chemistry, Memorial University of Newfoundland, St. John's, Canada

"…this book apparently helps not only newcomers but also experts for their technology review."

––Dr. Fumio Ueno, Chairman of IEC Technical Committee 105: Fuel Cell Technologies; Technology Executive, Micro Fuel Cell Display Devices & Components Control Center, Toshiba, Tokyo, Japan

"The author combines a clear and thorough understanding of the theoretical foundations of fuel cells with a sound application of these to the practical considerations and challenges of designing and operating fuel cell systems for a variety of applications."

––Dr. John F. Elter, President of Sustainable Systems LLC, Albany, New York, USA; Former Vice-President and CTO at Plug Power, Latham, New York, USA

"…it is a good reference for all levels of fuel cell developers. …The analysis on key issues for PEMFC applications is in-depth and thorough."

––Dr. Hao Tang, Chief Scientist, R&D Director, Alternative Energy Institute, China Eastern Electric Corp., Sichuan, China

"It provides information useful to beginners and experienced researchers alike. …It is a more comprehensive book [than] I have ever seen."

––Professor Pucheng Pei, Director, Institute of Automotive Power, Tsinghua University, Beijing, China
