Considerable efforts are being given to develop commercially viable technologies in order to alleviate the dependence on hydrocarbons as well as to reduce carbon dioxide emission by the use of fossil fuel. The proton exchange membrane fuel cell (PEMFC) has emerged as one of the most promising clean energy technology for residential and automotive applications. The high power density, low operating temperature, convenient fuel supply, longer lifetime, and modularity are the attractive features of PEMFC. This book covers the detailed methodology for development and characterization of composite...
