This book focuses on water content estimation and control of the PEM fuel cell stack and the individual cell in vehicle. Firstly, the mathematical connection between polarization curve and equivalent circuit model proves importance of MEA and its feasibility to study water content. Optimizing structure of MEA realizes the internal water content recirculation of a fuel cell and improves its performance under middle or lower current density. The influence of water content on performance of MEA is quantified, and variation of equivalent circuit model is an excellent indicator of water content. Secondly, the comprehensive online AC impedance measurement method is put forward, including current excitation method, weak voltage and current signal processing method, and method for analyzing measurement error, and experiment validates measurement accuracy. The high-frequency impedance and statistical characteristic are proposed as indicator of water content. Finally, the dynamic model of the air supply system of a fuel cell engine is established and the closed-loop control of the air supply system and the water content estimation are decoupled. The experiment on a fuel cell system validates the proposed method for searching optimized operating conditions and the water management strategy.

This book reviews the impact of water content in lithium-ion batteries (LIBs) as well as the reactivity of anodes, cathodes and electrolytes with water and processes that provide water-resistance to materials in LIBs. Water in LIBs which were constructed with anode, cathode and organic electrolyte containing lithium salts can degrade the cell performance and seriously damage the materials present. However, because a small amount of water in cells contributes to the formation of the solid electrolyte interphase, complete removal of water from cells lowers the battery performance and increases costs due to removal of water from the battery materials. This book presents the optimal concentration of water for each battery material along with appropriate removal methods and water-scavengers which were developed recently to establish both high performance and lower costs. Moreover this book describes the development of anodes and cathodes prepared by aqueous process and aqueous LIBs in which aqueous electrolytes containing lithium salts are used as an electrolyte. This book will be useful not only for academic researchers but also for company researchers who deal with LIBs.

This book deals with the electro-chemo-mechanical properties characteristic of and unique to solid electrode surfaces, covering interfacial electrochemistry and surface science. Electrochemical reactions such as electro-sorption, electro-deposition or film growth on a solid electrode induce changes in surface stress or film stress that lead to transformation of the surface phase or alteration of the surface film. The properties of solid electrode surfaces associated with the correlation between electrochemical and mechanical phenomena are named "electro-chemo-mechanical properties". The book first derives the surface thermodynamics of solid electrodes as fundamentals for understanding the electro-chemo-mechanical properties. It also explains the powerful techniques for investigating the electro-chemo-mechanical properties, and reviews the arguments for derivation of surface thermodynamics of solid electrodes. Further, based on current experimental findings and theories, it discusses the importance of the contribution of surface stress to the transformation of surface phases, such as surface reconstruction and underpotential deposition in addition to the stress evolution during film growth and film reduction. Moreover, the book describes the nano-mechanical properties of solid surfaces measured by nano-indentation in relation to the electro-chemo-mechanical properties. This book makes a significant contribution to the further development of numerous fields, including electrocatalysis, materials science and corrosion science.
