For full market implementation of PEM fuel cells to become a reality, two main limiting technical issues must be overcome- cost and durability. This cutting-edge volume directly addresses the state-of-the-art advances in durability within every fuel cell stack component. Designed to be relevant to the professional community, in addition to researchers, this book will serve as a valuable reference, featuring topics covered nowhere else, and a one-stop-shop to create a solid platform for understanding this important area of development. This reference covers aspects of durability in the entire fuel cell stack. Each chapter also includes vision of pathways forward and an explanation of the tools needed to continue along the path toward commercialization. It features expert insights from contributing authors who are key industrial and academic leaders in the field. It includes coverage of two key topics in the field - Testing and Protocol for Durability, and Computational Modeling Aspects of PEFC Durability - which are newly emerging, pivotally important subjects not systematically covered anywhere else. It undertakes aspects of durability across the entire fuel stack, from membranes to bipolar plates.
