Available in PDF, EPUB and Kindle. Book excerpt: Direct methanol fuel cells are seen as an attractive potential replacement for lithium ion batteries in small portable electronic devices. Crucial to the operation of direct methanol fuel cells is the proton exchange membrane, which conducts protons from the anode to the cathode, while acting as an insulator to electrons. The proton exchange membrane should also act as a physical barrier to the methanol and water at the anode, and the air or oxygen at the cathode, however the most commonly used proton exchange membrane, Nafion, suffers from significant methanol permeation from the anode to the cathode during operation. This work examined the effect of modifying Nafion membranes through in situ sol gel synthesis of silicon oxide nanoparticles with varying surface chemistry and microstructure. Detailed structural characterisation of the composite structure was undertaken using a wide variety of techniques including small angle X-ray and neutron scattering, wide-angle X-ray scattering, thermal analysis techniques and positron annihilation lifetime spectroscopy. Transport properties of the composite membranes were evaluated by impedance spectroscopy and pervaporation techniques.

Available in PDF, EPUB and Kindle. Book excerpt: From the late-1960’s, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The “gold standard’ amongst the many variations that exist today has been, and to a great extent still is, DuPont’s Nafion® family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments – es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. “Polymer Membranes in Fuel Cells” takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.

Book excerpt: The proton exchange membrane is one key component of direct methanol fuel cells, which has double functions of conducting protons, separating fuels and oxidant. At present, the performance and price of sulfonic acid proton exchange membrane used in direct methanol fuel cells are deeply concerned. In order to reduce membrane 's cost and improve performance of Nafion membrane, three different kinds of membranes have been studied in this thesis. These membranes are SPEEK membranes, SPEEK/ZP composite membranes and Nafion/ZP composite membranes.

Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the latest developments in the area of polymer electrolyte membranes (PEMs) used for high-temperature fuel cells. Featuring contributions from an international array of researchers, it presents a unified viewpoint on the operating principles of fuel cells, various methodologies used for the fabrication of PEMs, and issues related to the chemical and mechanical stabilities of the membranes. Special attention is given to the fabrication of electrospun nanocomposite membranes. The editors have consciously placed an emphasis on developments in the area of fast-growing and promising PEM materials obtained via hygroscopic inorganic fillers, solid proton conductors, heterocyclic solvents, ionic liquids, anhydrous H3PO4 blends, and heteropolyacids. This book is intended for fuel cell researchers and students who are interested in a deeper understanding of the organic–inorganic membranes used in fuel cells, membrane fabrication methodologies, properties and clean energy applications.

Book excerpt: Advances in Nanocomposites - Synthesis, Characterization and Industrial Applications was conceived as a comprehensive reference volume on various aspects of functional nanocomposites for engineering technologies. The term functional nanocomposites signifies a wide area of polymer/material science and engineering, involving the design, synthesis and study of nanocomposites of increasing structural sophistication and complexity useful for a wide range of chemical, physicochemical and biological/biomedical processes. "Emerging technologies" are also broadly understood to include new technological developments, beginning at the forefront of conventional industrial practices and extending into anticipated and speculative industries of the future. The scope of the present book on nanocomposites and applications extends far beyond emerging technologies. This book presents 40 chapters organized in four parts systematically providing a wealth of new ideas in design, synthesis and study of sophisticated nanocomposite structures.

This book was released on 2011 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a rise in demand for electricity and depletion of fossil fuel levels, researchers are looking for an alternative resource to generate power, one which is more environmentally friendly. Fuel cells are one of the best alternatives presently available and are considered by many to be the most promising energy sources with efficiencies of up to 60%. Presently, the cost associated with the usage of fuel cells available in the market is quite high. Researchers are trying to bring down costs associated with their usage and improve efficiency. PEM fuel cells are one of the most promising types of fuel cells. Researchers are currently trying to improve its efficiency by improving its electrolyte. Nafion® is one of the main electrolyte used in PEM fuel cells as it acts as proton conductor. Graphene has an exceptionally high surface area to volume ratio and excellent strength. Current research is focused on integrating graphene in PEM fuel cell electrolytes to improve performance. In this study, graphene is added to Nafion® in varying weight percentages to study the performance of the fuel cell given these changes. The graphene weight percentage is varied by 1, 2, 3, and 4. The fuel cell was operated and it was observed that with the addition of graphene there is an improvement in voltage, proton conductivity, and electron conductivity of the PEM fuel cell. The improvement of proton conductivity and electron conductivity followed a linear path with the increase in graphene weight percentage in the Nafion®. Physical properties of the Nafion® membrane with additional graphene were measured and found out that dielectric constant and thermal conductivity also improved linearly with an increase in graphene weight percentage.
