Tungsten Carbides as Anode Electrocatalyst of Direct Methanol Fuel Cell by Qiao Ren Pdf

Due to the steady depletion of mineral fuels and the environmental pollution from conventional engines, there have been great interests in developing fuel cells. At present, the direct methanol fuel cell (DMFC) is one of the leading fuel cell systems. Currently, the widely used electrocatalyst for the DMFC is the Pt/Ru bimetallic system. But the disadvantages of Pt/Ru catalyst are its high costs, and its susceptibility toward CO poisoning due to the strong chemisorption of CO. Therefore, an alternative electrocatalyst with the activity toward the dissociation of methanol and water is very desirable to facilitate the commercialization of DMFC. The transition metal carbides have been shown to exhibit catalytic properties similar to Pt-Group metals in reactions with hydrocarbon molecules. This work is to determine the feasibility of using WCs as an alternative anode catalyst. This work began by synthesizing and characterizing the PVD WC thin films, in order to bridge the materials gap between previous model crystal surfaces and the more realistic electrocatalysts. Fundamental surface science techniques where applied to examine the composition of the film. Ex situ cyclic voltammetry (CV) measurements have been applied to examine the electrocatalyst stability of the thin films. Supported WCs synthesized by temperature programmed reaction (TPR) technique was also used as a bridge material with a larger surface area than PVD thin films. Supported WC samples were also tested by surface science techniques. CV measurements were performed to examine the electrocatalyst stability and methanol oxidation in an electrochemical environment. In ex situ CV study, the solution is very complicated for deciding the activity of WC towards methanol oxidation. A gas phase reaction, cyclohexene self-hydrogenation as a probe reaction for WC reactivity was performed in a batch reactor with IR, in order to evaluate the dehydrogenation activity of WC and Pt-modified WC.

Direct Alcohol Fuel Cells: Materials, Performance, Durability and Applications begins with an introductory overview of direct alcohol fuel cells (DAFC); it focuses on the main goals and challenges in the areas of materials development, performance, and commercialization. The preparation and the properties of the anodic catalysts used for the oxidation of methanol, higher alcohols, and alcohol tolerant cathodes are then described. The membranes used as proton conductors in DAFC are examined, as well as alkaline membranes, focusing on the electrical conductivity and alcohol permeability. The use of different kinds of carbon materials as catalyst supports, gas diffusion layers, and current collectors in DAFC is also discussed. State of the art of the modeling is used to estimate performance and durability. The closing chapter reviews the use of DAFC in portable equipment and mobile devices and features a detailed discussion on the mechanisms of component degradation which limits their durability. This book is written to facilitate the understanding of DAFC technology, applications, and future challenges. It is an excellent introduction for electrochemical and material engineers interested in small fuel cells as portable energy sources, scientists focused on materials science for energy production and storage, as well as policy-makers in the area of renewable energies.

Direct Methanol Fuel Cells by Rose Hernandez,Caryl Dunning Pdf

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.

Nanomaterials for Direct Alcohol Fuel Cells by Fatih Sen Pdf

Nanomaterials for Direct Alcohol Fuel Cells explains nanomaterials and nanocomposites as well as the characterization, manufacturing, and design of alcohol fuel cell applications. The advantages of direct alcohol fuel cells (DAFCs) are significant for reliable and long-lasting portable power sources used in devices such as mobile phones and computers. Even though substantial improvements have been made in DAFC systems over the last decade, more effort is needed to commercialize DAFCs by producing durable, low-cost, and smaller-sized devices. Nanomaterials have an important role to play in achieving this aim. The use of nanotechnology in DAFCs is vital due to their role in the synthesis of nanocatalysts within the manufacturing process. Lately, nanocatalysts containing carbon such as graphene, carbon nanotubes, and carbon nanocoils have also attracted much attention. When compared to traditional materials, carbon-based materials have unique advantages, such as high corrosion resistance, better electrical conductivity, and less catalyst poisoning. This book also covers different aspects of nanocomposites fabrication, including their preparation, design, and characterization techniques for their fuel cell applications. This book is an important reference source for materials scientists, engineers, energy scientists, and electrochemists who are seeking to improve their understanding of how nanomaterials are being used to enhance the efficiency and lower the cost of DAFCs. Shows how nanomaterials are being used for the design and manufacture of DAFCs Explores how nanotechnology is being used to enhance the synthesis and catalysis processes to create the next generation of fuel cells Assesses the major challenges of producing nanomaterial-based DAFCs on an industrial scale
