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 Synopsis Hydrocarbon Polymer Electrolytes for Fuel Cell Applications by : Jinli Qiao
Download or read book Hydrocarbon Polymer Electrolytes for Fuel Cell Applications written by Jinli Qiao and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct methanol fuel cells (DMFCs), employing liquid methanol as a fuel, offer an attractive option in portable devices due to their simplicity in the system structure (easy storage and supply), no need for fuel reforming or humidification. For obtaining a higher power density, the membranes that show high proton conductivity, and at the same time, low methanol permeability are strongly desired. However, there is achieved only a little progress because of trade-off relations between these parameters. Also the membrane stability, particular to hydrolytic and chemical stability is recognised as a key factor that affects fuel cell performances. In the authors' recent work, they have been working on the design and the development of new families of cost-effective, readily prepared proton-conducting membranes based on chemically cross-linked PVA-PAMPS [poly(vinyl alcohol) and poly(2-acrylamido-2-methyl-1-propanesulfonic acid)] composites. The authors have first introduced new concepts of secondary polymer chains such as "binary chemical cross-linking" or "hydrophobiciser" and the "stabiliser"effect. Also, the authors have established a new concept of PVA-PAMPS based semi-interpenetrating polymer networks (semi-IPNs) by incorporating plasticizer variants R (R = poly(ethylene glycol)(PEG), poly(ethylene glycol) methyl ether (PEGME), poly(ethylene glycol) dimethyl ether (PEGDE), poly(ethylene glycol) diglycidyl ether (PEGDCE)) and poly(ethylene glycol)bis(carboxymethyl)ether (PEGBCME) as the third components. Incorporation of the above concepts promoted not only the high proton conductivity , flexibility with low methanol permeability (1/3 - 1/2 of Nafion 117 membrane), but also the excellent hydrolytic and the oxidative stability of PVA-PAMPS composites. The membrane electrode assembly (MEA) fabricated with PVA-PAMPS composites has been successfully established, which showed the similar open circuit voltage (OCV) to that of Nafion 115, and a power density 52 mW cm-2 at 80oC. A striking feature of the long-term test was that no appreciable decay of the current density was observed during the whole operation time longer than 130 hours at 50oC, and so was the power density. This book is the first time that such long-term operation of DMFC was reported since PVA-PAMPS composite are all hydrocarbon membranes made simply of aliphatic skeletons. They are very different from the perfluorosulfonic membranes such as Nafion, or other reported membranes with aromatic skeletons. Therefore this affords the PVA-PAMPS composites unique structure compared to most of the proposed membranes, which suggests the good candidacy of PVA-PAMPS composites when they are intended for use in low temperature DMFCs.

Book Synopsis Proton Exchange Membrane (PEM) in Fuel Cells by : Deepti Gautam
Download or read book Proton Exchange Membrane (PEM) in Fuel Cells written by Deepti Gautam and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present compilation describes the Proton Exchange Membranes or Polymer Electrolyte Membranes (PEMs) that are both under development and commercialized for Direct Methanol Fuel Cells (DMFCs). It also outlines the classification of various fuel cells and the proton exchange membranes through perfluorinated membranes, perfluorinated composite membranes, partially fluorinated membranes, non-fluorinated membranes and non-fluorinated composite membranes. Among all the classified membranes, the perfluorinated membranes are found to be having exceptional properties. The membranes which have been developed till date for commercial purposes, the perfluorinated membranes show complete ascendancy for DMFC, although each membrane has its own pros and cons. As no single membrane has emerged with the best qualities, this review illustrates the prospects of the currently known membranes for DMFC with respect to their characteristics and properties. The performances of the membranes are estimated based on their properties like thermal resistance, proton conductivity, methanol crossover, and the ability to retain in the fuel cell. This review highlights that hydrocarbon and composite membranes are found to be low cost membranes with low methanol crossover, high durability and their efficiency, which influence the fuel cell commercial market.
