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.

Available in PDF, EPUB and Kindle. Book excerpt: In Chapter One, L. Khotseng and G. Vaivars provide an overview of the recent advances in electrocatalysts for direct methanol fuel cells for both anode and cathode catalysts in order to present direct methanol fuel cells as an alternative power source for portable devices. In Chapter Two, Nobuyoshi Nakagawa, Mohammad Ali Abdelkareem, Takuya Tsujiguchi, and Mohd Shahbudin Masdar propose a fuel supply layer using a porous carbon plate (PCP) for DMFCs allowing for the use of high methanol concentrations. The proposed layer is comprised of a thin PCP layer, as well as a gap layer that has a mechanism to supply the methanol as a vapor. Next, Chapter Three by D.S. Falcão, J. P. Pereira, and A.M.F.R. Pinto review the multiphase flow in fuel cells modelling approaches while also reviewing the flow visualisation techniques for flow analysis in fuel cells. Chapter Four by B.A. Braz, V.B. Oliveira, and A.M.F.R. Pinto closes the book by discussing the key work that has been done to improve the passive DMFC performance and providing a review on the most recent developments in passive DMFCs.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The developed model can simulate the trend of the cell performance and water management of the stack by varying the key parameters, such as stack temperature, solution molarity, and the porosity of the LBL. The modeling results showed that the LBL has a more significant effect on the water balance and cell performance than the CGDL does. By increasing the porosity of the LBL 30%, the cell performance is increased significantly but the vent rate of the water vapor is also increased, resulting in a water-loss mode. The results also showed that a decrease of the porosity of the LBL enhances the water recovery of the stack, but that the cell performance is degraded.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this PhD thesis is the preparation and study of new materials to be used as electrolytes in Direct Methanol Fuel Cells (DMFC) in order to reduce crossover of methanol. Different materials have been prepared, including polymer dispersed liquid crystals, crosslinked polymers with high protonic conductivity and polymeric liquid crystals. Moreover, a methodology to characterise potential new materials for their application in DMFC has been developed. The absorption properties of water and methanol in the materials have been studied in different conditions and compared with the results obtained for commercial Nafion membranes used in DFMC. The absorption and diffusion properties of water and methanol through the materials have been studied by means of Fourier Transform Infrared Spectroscopy and thermal analysis techniques. The methodology provides important information to analyse the interactions between the different functional groups of the polymers and the solvents commonly used in DMFC. Finally, a device has been designed and set-up to analyse the effect on crossover of methanol of the electro-osmotic drag and the polarisation of the polymeric electrolytes.
