Book Description
Catalytic processing of fuels was explored in this thesis for both low-temperature polymer electrolyte membrane (PEM) fuel cell as well as high-temperature solid oxide fuel cell (SOFC) applications. Novel catalysts were developed to generate hydrogen for PEM applications from the oxidative steam reforming of methanol. The activity of lanthanum nickel perovskite (LaNiO3) was examined in both dilute fuel and full fuel conditions. Autothermal operation was successfully achieved with higher hydrogen selectivity than conventional Pd-based catalysts. The selected complex oxide catalyst was applied as a thin film onto a 0.2 [mu]m-thick Pd membrane. Pure hydrogen effluent was obtained from the resulting microreactor as desired for PEM applications. SOFC systems would be of interest for portable power generation if the thermal cycling and slow start-up issues could be addressed. One potential solution is the development of Si-supported ultrathin electrolyte structures (~100 nm-thick) of low thermal mass. Due to the low maximum fabrication temperature (

Book Description
Fuel cells are expected to play a major role in the future power supply that will transform to renewable, decentralized and fluctuating primary energies. At the same time the share of electric power will continually increase at the expense of thermal and mechanical energy not just in transportation, but also in households. Hydrogen as a perfect fuel for fuel cells and an outstanding and efficient means of bulk storage for renewable energy will spearhead this development together with fuel cells. Moreover, small fuel cells hold great potential for portable devices such as gadgets and medical applications such as pacemakers. This handbook will explore specific fuel cells within and beyond the mainstream development and focuses on materials and production processes for both SOFC and lowtemperature fuel cells, analytics and diagnostics for fuel cells, modeling and simulation as well as balance of plant design and components. As fuel cells are getting increasingly sophisticated and industrially developed the issues of quality assurance and methodology of development are included in this handbook. The contributions to this book come from an international panel of experts from academia, industry, institutions and government. This handbook is oriented toward people looking for detailed information on specific fuel cell types, their materials, production processes, modeling and analytics. Overview information on the contrary on mainstream fuel cells and applications are provided in the book 'Hydrogen and Fuel Cells', published in 2010.

Book Description
One-dimensional Nanostructures for PEM Fuel Cell Applications provides a review of the progress made in 1D catalysts for applications in polymer electrolyte fuel cells. It highlights the improved understanding of catalytic mechanisms on 1D nanostructures and the new approaches developed for practical applications, also including a critical perspective on current research limits. The book serves as a reference for the design and development of a new generation of catalysts to assist in the realization of successful commercial use that have the potential to decarbonize the domestic heat and transport sectors. In addition, a further commercialization of this technology requires advanced catalysts to address major obstacles faced by the commonly used Pt/C nanoparticles. The unique structure of one-dimensional nanostructures give them advantages to overcome some drawbacks of Pt/C nanoparticles as a new type of excellent catalysts for fuel cell reactions. In recent years, great efforts have been devoted in this area, and much progress has been achieved. Provides a review of 1D catalysts for applications in polymer electrolyte fuel cells Presents an ideal reference for the design and development of a new generation of catalysts to assist in the realization of successful commercial use Highlights the progress made in recent years in this emerging field
