This book presents, in a very comprehensive manner, the basic physical and mathematical laws that describe the electrochemical mechanisms that govern the performance of a proton exchange membrane fuel cell (PEMFC). These laws are used to develop an equivalent electric transient model of a PEMFC, suitable to be implemented in any commercially available electric circuit simulator software. In summary this book (1) looks into the history, main characteristics, classification, advantages and applications of fuel cells; (2) explores different modeling approaches, highlighting their most important...
