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.

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.

This book was released on 2004 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proton exchange membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC) are drawing much attention as alternative power sources for transportation, stationary, and portable applications. Nafion membranes are presently used in both PEMFC and DMFC as electrolytes, but are confronted with a few difficulties: (i) high cost, (ii) limited operating temperature of 100 °C, and (iii) high methanol permeability. With an aim to overcome some of the problems encountered with the Nafion membranes, this dissertation focuses on the design and development of a few materials systems for use in PEMFC and/or DMFC. The incorporation of hydrous Ta2O5·nH2O into Nafion membrane as well as the electrodes is shown to help the cell to retain water to higher temperatures. Membrane-electrode assembly (MEA) consisting of the composite membrane shows better cell performance at 100 and 110 °C than that with plain Nafion membrane, and a high power density of ~ 650 mW/cm2 at 100 °C is obtained with H2 - CO mixture as the fuel due to a significant alleviation of the CO poisoning of the catalysts. Sulfonated poly(etheretherketone) (SPEEK) membranes with various sulfonation levels are prepared and investigated in DMFC. With a sulfonation level of ~ 50 %, the SPEEK membranes exhibit low methanol permeability and electrochemical performance comparable to that of Nafion at around 60 °C, making it an attractive low-cost alternative to Nafion. From a comparative study of the structural evolutions with temperature in 2 M methanol solution, it is found that the lower methanol permeability of SPEEK membranes is related to the less connected and narrower pathways for water/methanol permeation. The dry proton conductor CsHSO4 shows a high proton conductivity of ~ 10−3 S/cm at temperatures 140 °C and water is not needed for proton conduction. However, it is found that CsHSO4 decomposes to Cs2SO4 and H2S at 150 °C in H2 atmosphere in contact with the Pt/C catalyst. Thus, new catalyst materials need to be explored for CsHSO4 to be used in practical high temperature PEMFC. Thin self-humidifying Nafion membranes with dispersed Pt/C catalyst powder are prepared and tested in PEMFC with dry H2 and O2. The Pt/C particles provide sites for catalytic recombination of H2 and O2 permeating from the anode and cathode, and the water produced at these sites directly humidifies the membrane. The performance of the cell with the self-humidifying membrane operated with dry reactants is ~ 90 % of that obtained with well humidified H2 and O2.
