Available in PDF, EPUB and Kindle. Book excerpt: This volume contains an archival record of the NATO Advanced Institute on Mini – Micro Fuel Cells – Fundamental and Applications held in Çesme – Izmir, Turkey, July 22–August 3, 2007. The ASIs are intended to be a high-level teaching activity in scientific and technical areas of current concern. In this volume, the reader may find interesting chapters on Mini- Micro Fuel Cells with fundamentals and applications. In recent years, fu- cell development, modeling and performance analysis has received much attention due to their potential for distributed power which is a critical issue for energy security and the environmental protection. Small fuel cells for portable applications are important for the security. The portable devices (many electronic and wireless) operated by fuel cells for providing all-day power, are very valuable for the security, for defense and in the war against terrorism. Many companies in NATO and non-NATO countries have concentrated to promote the fuel cell industry. Many universities with industrial partners committed to the idea of working together to develop fuel cells. As tech- logy advanced in the 1980s and beyond, many government organizations joined in spending money on fuel-cell research. In recent years, interest in using fuel cells to power portable electronic devices and other small equipment (cell phones, mobile phones, lab-tops, they are used as micro power source in biological applications) has increased partly due to the promise of fuel cells having higher energy density.

Download or read book Stackable Miniature Fuel Cells with On demand Fuel and Oxygen Supply written by Janet Hur and published by . This book was released on 2013 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation summarizes our progress towards miniature fuel cells that could replace and outperform small batteries to meet various power demands. With increasing need of power being critical for portable electronics, the demand for better batteries continues to grow. Lithium-ion batteries dominate the market at the moment, but the current capacities on the order of 200 Wh/kg are approaching their inherent limits. Many researchers have being pursuing alternative power sources, forming a rapidly growing field in engineering and science. For applications too small for batteries (below 1 cm and even 1 mm), currently no proper power source is available, despite over a decade of significant efforts by many in power micro electromechanical systems (power MEMS). Encouraged by the advantages of their macro counterparts, micro fuel cells have received attention as a potentially powerful, efficient, and clean power source for miniature applications, resulting in extensive research in micro fuel cells and even commercial introduction of some small fuel cells. However, they are not yet powerful enough to consider someday replacing batteries for a wide range of portable applications. While the promise of fuel cells is in their high theoretical energy density, unfortunately the promise is lost in current portable fuel cells because of their complex system that includes ancillary components such as mechanical pump, reformer, pressurized oxygen source, and gas separator. This dissertation summarizes our attempt to realize a full (i.e., complete, standalone) fuel cell with small footprint, extending the spirit of self-pumped fuel that eliminated ancillary components in the active fuel circulation system to self-controlled oxygen generation for a packaged oxidant supply. We first eliminate fuel pump, gas separator, membrane electrode assembly (MEA) and even pressurized oxygen tank to make anodic chamber simple and self-regulating. As the next step towards realizing a full fuel cell stackable as batteries, we develop a self-regulating oxygen generation system that supplies oxygen within the fuel cell, i.e., not relying on the ambient air. For our final goal, we integrate the self-pumped fuel supply and the self-regulated oxygen supply into one device to prove the concept of a full fuel cell suitable for a stacked configuration.

Download or read book Microbial Fuel Cell written by Debabrata Das and published by Springer. This book was released on 2017-12-01 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a novel attempt to describe microbial fuel cells (MFCs) as a renewable energy source derived from organic wastes. Bioelectricity is usually produced through MFCs in oxygen-deficient environments, where a series of microorganisms convert the complex wastes into electrons via liquefaction through a cascade of enzymes in a bioelectrochemical process. The book provides a detailed description of MFC technologies and their applications, along with the theories underlying the electron transfer mechanisms, the biochemistry and the microbiology involved, and the material characteristics of the anode, cathode and separator. It is intended for a broad audience, mainly undergraduates, postgraduates, energy researchers, scientists working in industry and at research organizations, energy specialists, policymakers, and anyone else interested in the latest developments concerning MFCs.
Download or read book Fuel Cell Micro grids written by Shin’ya Obara and published by Springer Science & Business Media. This book was released on 2008-10-03 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel Cell Micro-grids describes an energy supply method based on a network of two or more proton exchange membrane fuel cells (PEM-FC). Such a network enables the effective use of exhaust heat, the simplification of the transmission network, the possibility of backup during disruptive hazards and the consideration of regional factors. Furthermore, green energy and renewable energy systems can be connected to the network, to function in cooperation with the fuel cells. For these reasons, it is believed that an increasing number of applications will make use of such fuel cell energy networks. Fuel Cell Micro-grids analyses the operation plan of these new energy supply methods using genetic algorithms. The book explains the results of the analysis of the optimization operation plan, energy cost, and greenhouse gas discharge characteristics for many application cases of the fuel cell network.

Download or read book Proton Exchange Membrane Fuel Cells written by Inamuddin and published by John Wiley & Sons. This book was released on 2023-02-10 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: PROTON EXCHANGE MEMBRANE FUEL CELLS 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. 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.
