  • Chapter Three On the Prospects for Phosphonated Polymers as
           Proton-Exchange Fuel Cell Membranes
    • Abstract: 2007
      Publication year: 2007
      Source:Advances in Fuel Cells, Volume 1

      One of the major challenges in advancing polymer electrolyte membrane fuel cell technology lies currently in the development of new durable polymeric membranes that will allow fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized with covalently linked phosphonic acid may potentially show some crucial advantages in relation to the commonly employed sulfonated membranes. Because of the hydrogen bonding and amphoteric properties of the phosphonic acids, the former membranes may transport protons through structure diffusion under low-humidity conditions. At high water contents the protons may instead be transported through the dynamics of the water, much in the same way as in conventional sulfonated membranes. Furthermore, phosphonated polymers generally show a high hydrolytic and thermal stability due to the strength of the carbon-phosphorus bond, which is especially critical under high-temperature operation. However, it is clear that the molecular architecture of the phosphonated polymers will require a very careful design in order to reach these advantageous membrane properties. In addition, phosphonated polymers are in general more complicated to prepare than the corresponding sulfonated ones. The present treatise describes the nature of the phosphonic acids and critically surveys the current literature on synthetic approaches to useful phosphonated polymers and the properties of phosphonated membranes. The synthetic approaches include chemical modification of polymers by attaching phosphonic acid via alkyl, aryl and perfluoroalkyl groups, as well as direct polymerization using phosphonated monomers. In addition, some potential research directions for the development of new efficient fuel cell materials are outlined.

    • Abstract: 2007
      Publication year: 2007
      Source:Advances in Fuel Cells, Volume 1

      This review addresses polymer electrolytes that have been demonstrated in direct methanol fuel cells. This work reviews the material requirements of polymer electrolytes and gives an exhaustive overview of the polymer electrolyte membranes (PEMs) investigated specifically for direct methanol fuel cells (DMFCs). This chapter then provides a framework for interpreting the reported performance and potential of PEMs in DMFC applications. Finally, this review presents and compares currently reported performance of DMFCs, particularly those using alternative membranes with some discussion of future research directions.

  • Chapter Five Materials for State-of-the-Art PEM Fuel Cells, and Their
           Suitability for Operation Above 100°C
    • Abstract: 2007
      Publication year: 2007
      Source:Advances in Fuel Cells, Volume 1

      This review gives an overview of proton exchange membrane (PEM) fuel cells on the materials level. Materials for proton conducting membranes, electrodes and bipolar plates are described from the perspective of their suitability for longterm operation in automotive and stationary applications. The state-of-the-art PEM fuel cells consisting of perfluorosulfonic acid membranes, platinum-based electrodes and graphite(-composite)-based bipolar plates are in a well advanced state of development. Although the main constituents are in use for many years, impressive improvements in performance and lifetime have been realized, leading to cost reduction, size reduction, improved robustness and mass manufacturing. For the sake of system simplification, increasing the temperature of operation of the proton exchange membrane fuel cells (PEMFC) would be beneficial. New materials are needed to enable operation at higher tem- peratures, and not less important, lower relative humidities. The suitability of present state-of-the-art materials for operation above 100°C is discussed, as well as a critical review of the suitability of emerging concepts. No alternative material that combines the virtues of the present materials with the ability of operation above 100°C has been developed so far. Therefore, the first commercial introduction of PEM fuel cells is likely to be based on the components that are at present in use, making use of perfluorosulfonic acid membranes.

  • Chapter Six Analytical Models of a Direct Methanol Fuel Cell
    • Abstract: 2007
      Publication year: 2007
      Source:Advances in Fuel Cells, Volume 1

      The Chapter summarizes recent analytical and semi-analytical results obtained within the scope of one-dimensional (1D) and quasi two-dimensional (Q2D) isothermal models of a direct methanol fuel cell. 1D model takes into account the diffusive transport of methanol and oxygen to the catalyst sites, methanol permeation through the membrane (crossover), Tafel rate of feed molecules conversion in the electrochemical reactions and the direct catalytic methanol-oxygen combustion on the cathode side. Quasi-2D model in addition accounts for a variation of methanol and oxygen concentrations along the respective channel and the effect of gaseous bubbles in the anode channel. The procedure of models construction is described in detail and the physical processes, which stand behind model equations are discussed. The most striking result yields Q2D model, which shows that crossover leads to localization of current production close to the inlet of the oxygen channel. At constant oxygen stoichiometry the cell generates finite local current even at vanishingly small total current in the load. This effect explains lowering of cell open-circuit voltage (mixed-potential). Recent experimental studies of Ye, Zhao, Yang and Prabhuran (Electrochem. Solid State Lett. 8 (2005) A52), Muller, Dohle and Kulikovsky (Electrochem. Solid State Lett. 9 (2006) L7) and Kulikovsky et al (Electrochem. Comm. 8 (2006) 754) show that at open circuit the role of the load plays oxygendepleted part of the cell, which turns into electrolysis regime. CO2 bubbles in the anode channel dramatically reduce cell performance; however, under the shortage of oxygen the bubbles increase performance due to reduction of methanol crossover. The effect of non-Tafel kinetics of methanol oxidation on the anode catalyst layer performance is studies; the respective model reveals a novel regime of the active layer operation.

  • Chapter Seven Methanol Reforming Processes
    • Abstract: 2007
      Publication year: 2007
      Source:Advances in Fuel Cells, Volume 1

      Hydrogen is seen by many as the energy carrier for the future, and development of the science and technology needed to produce, store and utilize hydrogen has emerged as an international research priority. Hydrogen has the highest energy density of any non-nuclear fuel and can be easily converted to electrical and thermal energy via highly efficient, non-polluting processes. Fossil fuels like natural gas and crude oil are obvious sources for the large quantities of hydrogen needed to initiate the transition to a “Hydrogen Economy.” Hydrogen can be produced either off-board or on-board way. Most of the studies for on-board hydrogen production for fuel cells are based on two types of compounds. One is oxygen containing compounds — methanol and ethanol, etc. The other option is hydrocarbons such as natural gas, gasoline and diesel fuel. Among them, methanol is the most attractive fuel for on-board hydrogen production because of its high H/C ratio, low reforming temperature and good miscibility with water. In addition, methanol is sulfur-free, eliminating the concerns with catalyst or electrode poisoning by sulfur. The absence of carbon—carbon (C—C) bonds in methanol comparatively reduces the risk of coking. The different reforming process of methanol (steam reforming of methanol (SRM), partial oxidation of methanol (POM) and oxidative methanol reforming (OMR)) has been discussed and compared. Primarily owing to advances of the materials (e.g. catalysts) and reactors, the processing of hydrocarbons into H2-rich gas has become fairly efficient. The chapter focuses on the different catalysts of recent literature and reactors by different workers for hydrogen production from methanol reforming process and operation of fuel cells from the production of hydrogen in this process. The commercial catalyst for SRM is Cu/ZnO/Al2O3. The other types of catalyst like ZrO2 supported catalyst or addition of ZrO2 and CeO2 in Cu/ZnO/Al2O3, CuO/CeO2 and Pd/ZnO have also been discussed. The appropriate selection of reforming reactor is required for its suitability as on-board source of hydrogen in automobile industries as well as electronic equipment. The different approaches in this regard have been discussed. These are fixed bed reactor, monolithic reactor, wall-coated heat exchanger, micro-channel reactor and metallic foam reactor. Among them, micro-channel reactor seems to be most promising in portable electronics with respect to its fast response in transient behavior, higher heat (which will lead to better temperature control inside reactor) and mass transfer characteristics, less channeling of flow of reactant and less pressure drop. The further work on the stability of the coated catalyst with high catalytic performance is still required. The larger version of micro-channel reactor, i.e. wall-coated heat exchanger with channels can also be promising for automotive applications. Studies on the integrated operation of methanol reformer with the fuel cell is very essential to apply it in on-board application. It is evident from the existing literature that the methanol reformer has a desirable fast response to achieve the reaction temperature and is highly suitable for use with fuel cells to power automobiles. However, more efforts are still needed on the cold start and transient characteristics of the reformer if it is to be used as an on-board vehicle fuel processor.
