Fuel Cell Fundamentals. 2nd Edition
John Wiley and Sons Ltd, January 2009, Pages: 576
As the search for alternative fuels heats up, no topic is hotter than fuel cells. Filling a glaring gap in the literature, Fuel Cell Fundamentals, Second Edition gives advanced undergraduate and beginning level graduate students an important introduction to the basic science and engineering behind fuel cell technology. Emphasizing the foundational scientific principles that apply to any fuel cell type or technology, the text provides straightforward descriptions of how fuel cells work, why they offer the potential for high efficiency, and how their unique advantages can best be used. Designed to be accessible to fuel cell beginners, the text is suitable for any engineering or science major with a background in calculus, basic physics, and elementary thermodynamics. This new edition provides updated and enhanced examples, problems, and pedagogy for classroom use and features a significantly enlarged section on the practical applications of fuel cell technology. A solutions manual will be developed.
