Mini-Micro Fuel Cells


Book Description

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.

Hydrogen Technology


Book Description

Aline Leon ́ In the last years, public attention was increasingly shifted by the media and world governmentsto the conceptsof saving energy,reducingpollution,protectingthe - vironment, and developing long-term energy supply solutions. In parallel, research funding relating to alternative fuels and energy carriers is increasing on both - tional and international levels. Why has future energy supply become such a matter of concern? The reasons are the problems created by the world’s current energy supply s- tem which is mainly based on fossil fuels. In fact, the energystored in hydrocarb- based solid, liquid, and gaseous fuels was, is, and will be widely consumed for internal combustion engine-based transportation, for electricity and heat generation in residential and industrial sectors, and for the production of fertilizers in agric- ture, as it is convenient, abundant, and cheap. However, such a widespread use of fossil fuels by a constantly growing world population (from 2. 3 billion in 1939 to 6. 5 billion in 2006) gives rise to the two problems of oil supply and environmental degradation. The problemrelated to oil supply is caused by the fact that fossil fuels are not - newable primary energy sources: This means that since the rst barrel of petroleum has been pumped out from the ground, we have been exhausting a heritage given by nature.




Hydrogen and Fuel Cells


Book Description

A hydrogen economy, in which this one gas provides the source of all energy needs, is often touted as the long-term solution to the environmental and security problems associated with fossil fuels. However, before hydrogen can be used as fuel on a global scale we must establish cost effective means of producing, storing, and distributing the gas, develop cost efficient technologies for converting hydrogen to electricity (e.g. fuel cells), and creating the infrastructure to support all this. Sorensen is the only text available that provides up to date coverage of all these issues at a level appropriate for the technical reader. The book not only describes the "how" and "where" aspects of hydrogen fuels cells usage, but also the obstacles and benefits of its use, as well as the social implications (both economically and environmental). Written by a world-renowned researcher in energy systems, this thoroughly illustrated and cross-referenced book is an excellent reference for researchers, professionals and students in the field of renewable energy. Updated sections on PEM fuel cells, Molten carbonate cells, Solid Oxide cells and Biofuel cells Updated material to reflect the growing commercial acceptance of stationary and portable fuel cell systems, while also recognizing the ongoing research in automotive fuel cell systems A new example of a regional system based on renewable energy sources reflects the growing international attention to uses of renewable energy as part of the energy grid Examples of life cycle analysis of environmental and social impacts
