"Eisler’s book is more than a succinct history of the fuel cell itself. Just as important, it traces the history of the often utopian ideas behind this technology. This well-written and carefully researched study...helps the reader understand why the fuel cell has yet to fulfill its glittering promise. Overpotential provides a useful review of one technology whose various futures so far have failed to arrive."
~Chemical Heritage
"A very fine book. Overpotential unpacks the more complex, and infinitely more interesting, story of the intertwining of technological developments concerning electrical power and the search for new sources of cheap, safe, efficient electricity."
~Quest: The History of Spaceflight
"In this extensively researched and detailed book, Eisler provides the 'rest of the story' of fuel cells and fuel cell applications progress in the 20th century. Highly recommended."
~Choice
"In Overpotential, Matthew Eisler demonstrates that historians can and should contribute to the energy debate ... A major strength of the book is that it aims to — and largely does — bridge the gap between the fuel cell as history of technology and as present-day engineering and policy challenge."
~Technology and Culture
"Joining scholarly analysis with engaging narrative, Eisler exposes the perils of technology policy and reveals how a cult of innovation can trump socially sound energy policy in the United States."
~John M. DeCicco, University of Michigan
"Eisler's historical treatment of the engineering subject matter in Overpotential provides a perspective that is often lacking in the current discourse on fuel cells."
~Frederik Nebeker, author of Dawn of the Electronic Age
"Exaggerated claims made on behalf of new energy conversions are commonly met with uncritical acceptance. Eisler provides a much needed corrective, a well-informed and critical explanation of why fuel cells have not become a miraculous energy source."
~Vaclav Smil, University of Manitoba
