Fuel cell science and technology is evolving fast for the past two decades as it is thought to be an efficient way of transforming chemical energy of hydrogen rich compounds to electrical energy. Although this idea of direct conversion of chemical energy to electrical energy was first demonstrated by Sir William Grove in 1839 using a fuel cell, it was only in the middle of the twentieth century when Bacon's pioneering work led to the use of fuel cell in space missions. The interest in commercialization of fuel cell for civilian use has caught up with government organizations and private corporations for the past decade on account of fluctuating oil prices and environmental concerns. It is well known that the conventional fossil fuel, which is a primary source of gasoline, is not going to last more than a hundred years in the face of ever-increasing demand in the developed and developing countries. Although the reserves of natural gas, coal and tar sands may last another two to three hundred years with the current rate of production, their conversion is not efficient and pollution-free. Thus, scientists all over the world have taken up fuel cell development work in their quest of solution to the energy crises looming largely on global population. This book aims to script the present status of the rapidly developing field of fuel cell science and technology.

After completing Ph.D. (I.I.Sc., Bangalore) in Chemical Engineering, Dr. S. Basu joined Department of Chemical& Material Engineering, University of Alberta, Canada as post-doc fellow in 1994 and continued there as post-doc fellow and visiting faculty up to 1997. He joined Department of Chemical Engineering, Indian Institute of Technology Delhi as Assistant Professor in 1998. He initiated fuel cell development program at IIT Delhi with support of the Ministry of Nonconventional Energy Sources, India. Many Ph.D. students are working on these projects. He has published 25 papers in international journals with high citation index and presented 7 papers in international conferences and 6 in national conferences and one patent filed. He has visited University of Alberta, Canada in 2000 and 2002 as visiting Professor. Currently, he is executive council member of Indian Institute of Chemical Engineers (IIChE) and Hon. Secretary of IIChE, Northern Regional Centre.
