This book covers the proceedings of the 4th International Conference on Energy Systems, Drives, and Automations (ESDA2021). It comprises interesting topics in renewable energy, power management, drives of electrical machines, and automation. It also discusses different tools and techniques to match the conference theme. This book also comprehensively discusses related tools and techniques and is a valuable resource for researchers and professionals in electrical and mechanical engineering disciplines.

This book is a comprehensive review of high-temperature polymer electrolyte membrane fuel cells (PEMFCs). PEMFCs are the preferred fuel cells for a variety of applications such as automobiles, cogeneration of heat and power units, emergency power and portable electronics. The first 5 chapters of the book describe rationalization and illustration of approaches to high temperature PEM systems. Chapters 6 - 13 are devoted to fabrication, optimization and characterization of phosphoric acid-doped polybenzimidazole membranes, the very first electrolyte system that has demonstrated the concept of and motivated extensive research activity in the field. The last 11 chapters summarize the state-of-the-art of technological development of high temperature-PEMFCs based on acid doped PBI membranes including catalysts, electrodes, MEAs, bipolar plates, modelling, stacking, diagnostics and applications.

This book dedicates to publish exceptionally important and high-quality, agenda-setting research so as to tackle the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The book appeals to chemical scientists, chemical and process engineers, energy researchers, bio-scientists, and environmental scientists from across academia, industry, and government. The scope is intentionally broad, and the book recognizes the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies, and environmental science. The main topics of this book include but not limit to (1) alternative energy and the environment, (2) assessments of the condition of ecosystems and environmental quality, (3) behavior of and impacts of pollutants in atmosphere, soil, and water, (4) management of ecosystems, environment, and water resources, (5) modeling and regional environmental assessments (includes global change), (6) treatment/restoration of ecosystems, environment, and water resources, and (7) sustainable/renewable energy. All scales of studies and analysis, from impactful fundamental advances to interdisciplinary research across the (bio)chemical, (bio/geo) physical sciences, and chemical engineering disciplines are welcomed. So, this book is linked to the energy-environment nexus and is of significant general interest to our community-spanning readership.

Over the past decade the topic of energy and environment has been acknoedged among many people as a critical issue to be solved in 21st century since the Kyoto Protocol came into in 1997.

This book introduces high-temperature shock technology (HTS), a new method for ultra-fast synthesis of nanomaterials. HTS cannot only effectively avoid surface oxidation, agglomeration and immiscibility during the preparation of nanomaterials but also eliminate the defects or impurities of carbon-based nanomaterials. The book first presents the unique working devices of HTS. Then, it explains the working principle of its rapid heating and cooling rate at the millisecond level. In addition, the book highlights the latest research achievements of this technology in catalysis, batteries, carbon materials and new material devices, and puts forward the cost-benefit analysis and future development direction. Given its scope, the book appeals to a broad readership, particularly researchers engaged in materials, chemistry, new energy and other related fields, as well as teachers of relevant majors in colleges and universities.

This book introduces readers to the preparation of metal nanocrystals and its applications. In this book, an important point highlighted is how to design noble metal nanocrystals at the atomic scale for energy conversion and storage. It also focuses on the controllable synthesis of water splitting electrode materials including anodic oxygen evolution reaction (OER) and cathode hydrogen evolution reaction (HER) at the atomic level by defect engineering and synergistic effect. In addition, in-situ technologies and theoretical calculations are utilized to reveal the catalytic mechanisms of catalysts under realistic operating condition. The findings presented not only enrich research in the nano-field, but also support the promotion of national and international cooperation.

This book focuses on nanocarbons (carbon nanotubes, graphene, nanoporous carbon, and carbon black) and related materials for energy conversion, including fuel cells (predominately proton exchange membrane fuel cells [PEMFC]), Li-ion batteries, and supercapacitors.
