PROTON EXCHANGE MEMBRANE FUEL CELLSEdited by one of the most well-respected and prolific engineers in the world and his team, this book provides a comprehensive overview of hydrogen production, conversion, and storage, offering the scientific literature a comprehensive coverage of this important fuel.Proton exchange membrane fuel cells (PEMFCs) are among the most anticipated stationary clean energy devices in renewable and alternative energy. Despite the appreciable improvement in their cost and durability, which are the two major commercialization barriers, their availability has not matched demand. This is mainly due to the use of expensive metal-catalyst, less durable membranes, and poor insight into the ongoing phenomena inside proton exchange membrane fuel cells. Efforts are being made to optimize the use of precious metals as catalyst layers or find alternatives that can be durable for more than 5000 hours.Computational models are also being developed and studied to get an insight into the shortcomings and provide solutions. The announcement by various companies that they will be producing proton exchange membrane fuel cells-based cars by 2025 has accelerated the current research on proton exchange membrane fuel cells. The breakthrough is urgently needed. The membranes, catalysts, polymer electrolytes, and especially the understanding of diffusion layers, need thorough revision and improvement to achieve the target. This exciting breakthrough volume explores these challenges and offers solutions for the industry. Whether for the student, veteran engineer, new hire, or other industry professionals, this is a must-have for any library.

Edited by one of the most well-respected and prolific engineers in the world and his team, this book provides a comprehensive overview of hydrogen production, conversion, and storage, offering the scientific literature a comprehensive coverage of this important fuel. Continually growing environmental concerns are driving every, or almost every, country on the planet towards cleaner and greener energy production. This ultimately leaves no option other than using hydrogen as a fuel that has almost no adverse environmental impact. But hydrogen poses several hazards in terms of human safety as its mixture of air is prone to potential detonations and fires. In addition, the permeability of cryogenic storage can induce frostbite as it leaks through metal pipes. In short, there are many challenges at every step to strive for emission-free fuel. In addition to these challenges, there are many emerging technologies in this area. For example, as the density of hydrogen is very low, efficient methods are being developed and engineered to store it in small volumes. This groundbreaking new volume describes the production of hydrogen from various sources along with the protagonist materials involved. Further, the extensive and novel materials involved in conversion technologies are discussed. Also covered here are the details of the storage materials of hydrogen for both physical and chemical systems. Both renewal and non-renewal sources are examined as feedstocks for the production of hydrogen. The non-renewal feedstocks, mainly petroleum, are the major contributor to date but there is a future perspective in a renewal source comprising mainly of water splitting via electrolysis, radiolysis, thermolysis, photocatalytic water splitting, and biohydrogen routes. Whether for the student, veteran engineer, new hire, or other industry professionals, this is a must-have for any library.

BIODEGRADABLE MATERIALS AND THEIR APPLICATIONSBiodegradable materials have ascended in importance in recent years and this book comprehensively discusses all facets and applications in 29 chapters making it a one-stop shop.Biodegradable materials have today become more compulsory because of increased environmental concerns and the growing demand for polymeric and plastic materials. Despite our sincere efforts to recycle used plastic materials, they ultimately tend to enter the oceans, which has led to grave pollution. It is necessary, therefore, to ensure that these wastes do not produce any hazards in the future. This has made an urgency to replace the synthetic material with green material in almost all possible areas of application.Biodegradable Materials and Their Applications covers a wide range of subjects and approaches, starting with an introduction to biodegradable material applications. Chapters focus on the development of various types of biodegradable materials with their applications in electronics, medicine, packaging, thermoelectric generations, protective equipment, films/coatings, 3D printing, disposable bioplastics, agriculture, and other commercial sectors. In biomedical applications, their use in the advancement of therapeutic devices like temporary implants, tissue engineering, and drug delivery vehicles are summarized.AudienceMaterials scientists, environmental and sustainability engineers, and any other researchers and graduate students associated with biodegradable materials.
