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. [...] chapters on durability in the individual fuel cell components -- membranes, electrodes, diffusion media, and bipolar plates -- highlight specific degradation modes and mitigation strategies. The book also includes chapters which synthesize the component-related failure modes to examine experimental diagnostics, computational modeling, and laboratory protocol"--Back cover.
In this handbook and ready reference, editors and authors from academia and industry share their in-depth knowledge of known and novel materials, devices and technologies with the reader. The result is a comprehensive overview of electrochemical energy and conversion methods, including batteries, fuel cells, supercapacitors, hydrogen generation and storage as well as solar energy conversion. Each chapter addresses electrochemical processes, materials, components, degradation mechanisms, device assembly and manufacturing, while also discussing the challenges and perspectives for each energy storage device in question. In addition, two introductory chapters acquaint readers with the fundamentals of energy storage and conversion, and with the general engineering aspects of electrochemical devices. With its uniformly structured, self-contained chapters, this is ideal reading for entrants to the field as well as experienced researchers.
Contains papers from five separate symposia of the 194th Meeting of the Electrochemical Society in Boston, Massachusetts, in November 1998. Papers reflect recent findings in aqueous batteries, battery applications, batteries for the 21st century, corrosion in batteries and fuel cells, and exploratory research and development of batteries and supercapacitors for electric and hybrid vehicles. Specific topics include nickel hydroxide and manganese dioxide electrode materials and compositions in primary and rechargeable batteries, power source modeling and performance, novel high voltage cathode materials, microbatteries, and lithium polymer electrolyte batteries.

Electrochemical Power Sources (EPS) provides in a concise way theoperational features, major types, and applications of batteries,fuel cells, and supercapacitors • Details the design, operational features, andapplications of batteries, fuel cells, and supercapacitors • Covers improvements of existing EPSs and thedevelopment of new kinds of EPS as the results of intense R&Dwork • Provides outlook for future trends in fuel cells andbatteries • Covers the most typical battery types, fuel cells andsupercapacitors; such as zinc-carbon batteries, alkaline manganesedioxide batteries, mercury-zinc cells, lead-acid batteries, cadmiumstorage batteries, silver-zinc batteries and modern lithiumbatteries
This book reviews research work on electrochemical power sources in the former Warsaw Pact countries. It explores the role carbon plays in the cathodes and anodes of power sources and reveals the latest research into the development of metal air batteries, supercapacitors, fuel cells and lithium-ion and lithium-ion polymer batteries. For the first time, a full chapter was devoted to metal-carbon composites as electrode materials of lithium-ion batteries
This book covers a significant number of R&D projects, performed mostly after 2000, devoted to the understanding and prevention of performance degradation processes in polymer electrolyte fuel cells (PEFCs). The extent and severity of performance degradation processes in PEFCs were recognized rather gradually. Indeed, the recognition overlapped with a significant number of industrial dem- strations of fuel cell powered vehicles, which would suggest a degree of technology maturity beyond the resaolution of fundamental failure mechanisms. An intriguing question, therefore, is why has there been this apparent delay in addressing fun- mental performance stability requirements. The apparent answer is that testing of the power system under fully realistic operation conditions was one prerequisite for revealing the nature and extent of some key modes of PEFC stack failure. Such modes of failure were not exposed to a similar degree, or not at all, in earlier tests of PEFC stacks which were not performed under fully relevant conditions, parti- larly such tests which did not include multiple on–off and/or high power–low power cycles typical for transportation and mobile power applications of PEFCs. Long-term testing of PEFCs reported in the early 1990s by both Los Alamos National Laboratory and Ballard Power was performed under conditions of c- stant cell voltage, typically near the maximum power point of the PEFC.
