PEM Fuel Cell Diagnostic Tools presents various tools for diagnosing PEM fuel cells and stacks, including in situ and ex situ diagnostic tools, electrochemical techniques, and physical/chemical methods. The text outlines the principles, experimental implementation, data processing, and application of each technique, along with its capabilities and weaknesses.The book covers many diagnostics employed in the characterization and determination of fuel cell performance. It discusses commonly used conventional tools, such as cyclic voltammetry, electrochemical impedance spectroscopy, scanning electron microscopy, and transmission electron microscopy. It also examines special tools developed specifically for PEM fuel cells, including transparent cells, cathode discharge, and current mapping, as well as recent advanced tools for diagnosis, such as magnetic resonance imaging and atomic force microscopy. For clarity, the book splits these diagnostic methodologies into two parts—in situ and ex situ. To better understand the tools, PEM fuel cell testing is also discussed. Each self-contained chapter provides cross-references to other chapters.Written by international scientists active in PEM fuel cell research, this volume incorporates state-of-the-art technical advances in PEM fuel cell diagnosis. The diagnostic tools presented help readers to understand the physical and chemical phenomena involved in PEM fuel cells.

PEM Fuel Cell Failure Mode Analysis presents a systematic analysis of PEM fuel cell durability and failure modes. It provides readers with a fundamental understanding of insufficient fuel cell durability, identification of failure modes and failure mechanisms of PEM fuel cells, fuel cell component degradation testing, and mitigation strategies against degradation.The first several chapters of the book examine the degradation of various fuel cell components, including degradation mechanisms, the effects of operating conditions, mitigation strategies, and testing protocols. The book then discusses the effects of different contamination sources on the degradation of fuel cell components and explores the relationship between external environment and the degradation of fuel cell components and systems. It also reviews the correlation between operational mode, such as start-up and shut-down, and the degradation of fuel cell components and systems. The last chapter explains how the design of fuel cell hardware relates to failure modes.Written by international scientists active in PEM fuel cell research, this volume is enriched with practical information on various failure modes analysis for diagnosing cell performance and identifying failure modes of degradation. This in turn helps in the development of mitigation strategies and the increasing commercialization of PEM fuel cells.

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 relevance to renewable energy sources. PEM Electrolysis for Hydrogen Production: Principles and Applications discusses the advantages of PEM electrolyzers over alkaline electrolyzers, presents the recent advances of hydrogen PEM fuel cells accelerating the large-scale commercialization of PEM electrolysis, and considers the challenges that must be addressed before PEM electrolysis can become a commercially feasible option. Written by international scientists in PEM electrolysis and fuel cell research areas, this book addresses the demand for energy storage technologies that store intermittent renewable energy and offers the most complete and up-to-date information on PEM electrolysis technology and research. The authors: Cover the fundamental applications of PEM electrolysisReview the state-of-the-art technologies and challenges related to each of the components of the PEM electrolysisAddress failure analysis and review available failure diagnostic toolsProvide future direction for researchers and technology developersPEM Electrolysis for Hydrogen Production: Principles and Applications provides a fundamental understanding of the requirements and functionalities of certain components and attributes of the PEM electrolysis technology that are common for both PEM fuel cells’ and electrolyzers’ hydrogen applications for energy storage. Beneficial to students and professionals, the text serves as a handbook for identifying PEM electrolysis failure modes and diagnosing electrolyzer performance to improve efficiency and durability.
