Book excerpt: Ion irradiation has been investigated as a route for the preparation of mechanically stable and highly durable cross linked sulphonated PEEK for fuel cell application. The formation of cross linking was confirmed by solvent extraction using the well known Charlsby- inner equation. The DSC results indicated that the cross links retard the crystallization, but no changes were observed in the mechanism of crystallization. The thermal kinetic data for irradiated PEEK quantitatively suggest that these films still have sufficient thermal stability for long term applications as fuel cell membranes. Analysis of the dielectric response by Cole-Cole, Havrilak and Negami and Williams and Watts equations indicated that the dipole relaxation was broadened and becoming more asymmetric with cross link density. The sulphonation of the cross linked PEEK in concentrated sulphuric acid indicated that the rate of reaction decreased with cross linking density and was consistent with diffusion control kinetics. Increasing cross link density resulted in more bound water in the equilibrated membranes and the nano-structure present was comparable to that of Nafion. Cross linking improved the chemical stability of PEMs in particular in methanol solution. The measurement of power output and energy efficiency suggested that the cross linked PEMs produced are promising candidates to replace Nafion membranes but more information are required, in particular on their long term stability under fuel cell operating conditions.

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.

This book was released on 2010 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The decreasing availability of fossil fuels and the increasing impact of greenhouse gases on the environment lead to an extensive development of more efficient or renewable energy sources. The direct alcohol fuel cell (DAFC) as a portable energy source is a promising and fast growing technology which meets these demands. Up to now, methanol is mostly studied as a fuel for these devices, however, applying ethanol has some evident advantages over methanol. The major challenges in direct ethanol fuel cell (DEFC) research on component level are the catalyst development and the electrolyte membrane development. The focus of this thesis lies on the development and characterization of proton conductive membranes for application in direct ethanol fuel cells (DEFC). Sulfonated poly(ether ether ketone) (sPEEK) based organic-inorganic mixed-matrix membranes are developed and, in addition, the inorganic phase is modified with functional silanes carrying basic groups. The membranes are characterized with respect to fuel crossover, proton conductivity, membrane stability and direct ethanol fuel cell tests.

Available in PDF, EPUB and Kindle. Book excerpt: PEM Fuel Cell Failure Mode Analysis presents a systematic analysis of PEM fuel cell durability and failure modes. It provides readers with a fundamental understanding of insufficient fuel cell durability, identification of failure modes and failure mechanisms of PEM fuel cells, fuel cell component degradation testing, and mitigation strategies against degradation. The first several chapters of the book examine the degradation of various fuel cell components, including degradation mechanisms, the effects of operating conditions, mitigation strategies, and testing protocols. The book then discusses the effects of different contamination sources on the degradation of fuel cell components and explores the relationship between external environment and the degradation of fuel cell components and systems. It also reviews the correlation between operational mode, such as start-up and shut-down, and the degradation of fuel cell components and systems. The last chapter explains how the design of fuel cell hardware relates to failure modes. Written by international scientists active in PEM fuel cell research, this volume is enriched with practical information on various failure modes analysis for diagnosing cell performance and identifying failure modes of degradation. This in turn helps in the development of mitigation strategies and the increasing commercialization of PEM fuel cells.
