The second edition of introduction to electrochemical science and engineering outlines the basic principles and techniques used in the development of electrochemical engineering related technologies, such as fuel cells, electrolyzers, and flow-batteries. Covering topics from electrolyte solutions to electrochemical energy conversion systems and corrosion, this revised and expanded edition provides new educational material to help readers familiarize themselves with some of today’s most useful electrochemical concepts. The second edition includes a new appendix c with a detailed description of how the most common electrochemical laboratories can be organized, what data should be collected, and how the data should be treated and presented in a report. Video demonstrations for these laboratories are available on youtube. In addition, the author has added conceptual and numerical exercises to all of the chapters to help with the understanding of the book material and to extend the important aspects of the electrochemical science and engineering.
