DESCRIPTION Multiscale Modeling of Electrochemical Reactions and Processes is a practical guide to multiscale computational methodologies. It offers a holistic understanding of the impact of reaction conditions on the overall performance of electrolyzers, fuel cells, and energy storage devices. This book covers reaction conditions such as electrolyte and applied bias potential and support type, as well as how these factors determine the overall performance of devices. These topics, for the first time, are covered in one book. This book presents: • A comprehensive examination of the experiment-theory gap of electrochemical reactions • State-of-the-art multiscale methods for modeling the influence of reaction environment, including electrolyte, bias potential, and support type, on the energy conversion efficiency in electrochemical cells. • A discussion of how to apply these multiscale modeling techniques to various applications in clean energy technology Multiscale Modeling of Electrochemical Reactions and Processes serves as a valuable resource for scientists, engineers, and students interested in electrochemistry, multiscale modeling, and clean energy applications. It is also a resource for the increasing number of available courses on materials modeling.
