There is no doubt that the world needs a secure supply of clean energy for the future. Fuel cells qualify as the ideal delivery mechanism. They are electrochemical devices capable of directly converting any consumable fuel to electrical energy through a chemical reaction. The only by-products are heat, carbon dioxide and water, which are considered to be environmentally safe. Fuel cells are efficient, clean, safe and reliable. Fuel Cells: Principles and Applications provides a snapshot of the present status of this rapidly progressing field: the ongoing breakthroughs in research and development, the directions for the future, and the proactive work of several firms in commercially producing fuel cell systems The book is a comprehensive reference book, explaining concepts and their applications. The interdisciplinary approach that draws on and clarifies the most recent research trends, makes this book interesting to everyone who is concerned with energy demands and fuel cells.
