CHAPTER 1
DOE R & D Fuel Cell Activities: Transportation, fixed and portable power applications
Terry Payne, PhD, PE, director of technology development, and Nancy Garland, PhD, Acting Team Leader of fuel cells, Office of hydrogen Fuel Cells and Infrastructure Technologies, U.S. Department of Energy
The Department of hydrogen program of energy launch of new research and development projects aimed at reducing component cost and increased battery durability and performance of transport and stationary fuel cells. Update on progress in the program including highlights new projects include the operation of a membrane electrode assembly in 7300 with the cycling voltage. market transformation activities in the program such as forklifts for distribution centers and fuel cells for standby power will be discussed.

CHAPTER 2
Schematic development of FCV Nissan - Current Status and Future
Adjemian Kev, Nissan Research Center, Nissan Motor Co., Ltd., Japan
Nissan Motor Company has recently developed their last generation of cell-house has many improvements over the previous generation. Compared to the old battery, this design doubled the power density and offer a longer service life while reducing overall costs. This was accomplished with the development a metal separator ultra-thin, which increased the maximum power of 40 kW for a total of 130 kW. In addition, the use of platinum was halved resulting in both increased longevity and reduced costs. Future research will focus on improvements additional battery and the system to achieve FCV commercialization under the Nissan Green Program.

CHAPTER 3
Degradation Media gas diffusion
Rod Borup, PhD, Institute of Cell and Hydrogen Fuel Fuel Cell Program Manager, Team Leader of fuel cells, Los Alamos National Laboratory *
Gas diffusion layer (GDL) degradation during the life of a PEM system can play an important role in overall system performance. CDG tend to show lower hydrophobicity during the operational life, changing the operating characteristics of the fuel cell with respect to water removal and power density. aging conditions varies the degree of loss of hydrophobicity GDL, while exposure to contamination have been shown to both decrease and increase hydrophobicity. To understand the degradation of the GDL, we use a number of characterization methods, including measures of energy surface, contact angle, particle size, elemental analysis, FTIR microscopy and in situ tests HR. * In collaboration with: J. Davey, LANL, D. Wood Cabot Corp.

CHAPTER 4
An inside look at the breakdown lane of a polymer electrolyte-electrode interface
Sanjeev Mukerjee, PhD, Professor, Director, Center for Renewable Energy Technology, Northeastern University
This chapter provides an in-depth some degradation processes most important in PEM fuel cells based on the oxidation of H2 and fuel line. observations of real life degradation of ionomer / membrane, changes in interfacial structure, disabling electrocatalyst, sintering will be discussed in the context Variable fuel cell operation. These include, overvoltage, start / stop, temperature and relative humidity. Choice of materials, such as mixtures ionomer membrane chemistry, catalyst support and the nature of reaction centers will be juxtaposed with the prospect mechanistic their time in lifting. This class is in a state where there are increased expectations on price and durability, an objective look at these applications in terms of what is possible is paramount and the stated objective underlying this presentation.

CHAPTER 5
The stability of platinum and carbon electrodes in PEMFC: Insight obtained by using electrochemical methods
A. Frank de Bruijn, PhD, Manager the hydrogen plant and fossil fuels, energy research Centre of the Netherlands (ECN), The Netherlands *
The stability of platinum on carbon electrodes is studied by measuring the mass of the electrodes at constant potential with high accuracy by using quartz crystal microbalance and combining with cyclic voltammetry at frequent intervals. Studies on platinum, carbon and platinum catalysts for carbon / revealed that platinum can dissolve in less than 90 hours almost completely under conditions that correspond to open circuit hot. In these conditions, carbon is oxidized quinone slowly, and then be oxidized to CO2. Lowering the temperature of 80 ˚ C to 60 ˚ C to cause a drastic reduction in speed dissolution of platinum avoid open circuit conditions at high temperature could lead to a lifetime much longer fuel cell EMP. * In collaboration with: VATDam

CHAPTER 6
MEA durability test system (MEADS)
Marianne Rodgers, PhD, Scientific Project Manager, Florida Solar Energy Center, and Kevin Cooper, PhD, principal investigator, Scribner Associates Inc. *
Staff Assembly membrane electrode assemblies (MEA) durability of a fuel cell requires the occupation of testing stations for long periods time. However, sustainability is important to study because, with the performance and cost, it is a limiting factor in the proton exchange membrane commercialization of fuel cells. The MEA Durability Test System (MEADS) (Scribner Associates Inc.) is designed for both old subject in the cells test sub-scale operating conditions fixed and stable. It conducts trials in parallel up to eight cells simultaneously. Each cell is used to control the flow of reactants, temperature, and the anode and cathode dew points. The MEADS system control software maintains uniform testing and continuous multiple MEAs when taking any cell off-line, the rapid execution of cell purging with N2, the evolution reagents, or perform OCV and / or current control. The use of MEADS will greatly facilitate MEA durability tests at Florida Solar Energy Center. * In collaboration with: L. Bonville, D. Slattery, J. Fenton, Florida Solar Energy Center.

CHAPTER 7
Performance and durability the fuel cell Flowfield Open Architecture
Amedeo Conti, PhD, Group Director of Electrochemical Technology, Nuvera Fuel Cells
Cell Technology Nuvera Fuel uses a porous metal structure as the key element of the bipolar plate flowfield multifunctional Assembly /. This approach design offers significant advantages in terms of mass transfer increased intensive management of densities, high efficiency at low load, and water / Ice during the freeze starts. This presentation will discuss recent results obtained by Nuvera as part of its investigation sustainability. Tests in different protocols will be presented, including: operation in the quasi-steady, rapid cycling, and begins to freeze. Correlation between data and models will be described. Different cell architectures are compared, and the future direction of Nuvera will be highlighted.

CHAPTER 8
Ovonic Metal Hydride Fuel Cell (MHFC) - The power of PEM at a fraction of the cost '
Rob Privett, Director, Development products, Ovonic Fuel Cell Company, a subsidiary of conversion devices Energy
Ovonic Battery MHFC offers typical power densities PEMFC fixed using non-platinum catalysts and inherently rapid alkaline chemical kinetics. The cost is much lower than other cell technologies competitive fuel avoiding Pt-group metals and using well known manufacturing industrial batteries. Instant start and low capacity temperature are well suited for portable applications and back-up. The durability of batteries MHFC was dominated by the effects of the cathode. New MO / catalysts carbon showed a stable performance indicating greatly improved the sustainability of a stabilization of the catalyst on the carbon substrate. Ovonic also looks effect on carbon dioxide which can degrade the electrodes mechanically
