The papers included in this issue of ECS Transactions were originally presented in the symposium ¿Electrochemistry: Symposium on Interfacial Electrochemistry in Honor of Brian E. Conway¿, held during the 216th meeting of The Electrochemical Society, in Vienna, Austria from October 4 to 9, 2009.

An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been used in the production of hydrogen for many years, there are certain advantages associated with PEM electrolysis and its relevan

The world’s largest economies have set clear development plans for hydrogen energy. From an Economy, Energy, and Environment (3E) point of view, hydrogen energy can be considered an ideal technology for enabling the energy transition from fossil fuels, restructuring energy systems, securing national energy sources, accelerating carbon neutralization, and driving the development of technologies and industry. Green hydrogen production by water electrolysis is the key for hydrogen energy, and this book offers urgently needed guidance on the most important scientific fundamentals and practical applied technologies in this field. This book: • Details materials, electrochemistry, and mechanics. • Covers ALK, PEM, AEM, and SOEC water electrolysis, including fundamentals and applications. • Addresses trends, opportunities, and challenges. This comprehensive reference is aimed at engineers and scientists working on renewable and alternative energy to meet global energy demands and climate action goals.

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M.

White Preface to Volume 8 Experimental methods in electrochemistry are becoming more diverse. This volume describes many of the new techniques that are being used as well as some of the well-established techniques. It begins with two chapters (1 and 2) on electronic instrumentation and methods for utilization of microcomputers for experimental data acquisition and reduction. Next, two chapters (3 and 4) on classical methods of electrochemical analysis are presented: ion selective electrodes and polarography.

This book presents a complete overview of the powerful but often misused technique of Electrochemical Impedance Spectroscopy (EIS). The book presents a systematic and complete overview of EIS. The book carefully describes EIS and its application in studies of electrocatalytic reactions and other electrochemical processes of practical interest. This book is directed towards graduate students and researchers in Electrochemistry. Concepts are illustrated through detailed graphics and numerous examples. The book also includes practice problems. Additional materials and solutions are available online.
