Novel Composite Membranes Containing Functionalised Silsesquioxanes and Ionic Liquids for High Temperature Fuel Cell Applications

Dutta N., Roy Choudhury N., Subianto S., Mistry M., Ian Wark Research Institute, AU

Today most of our energy supply comes from non-renewable energy resources such as fossil fuels, but there is an increasing drive towards the use of more environmentally friendly, renewable energy source. Of these alternative energies, [...]

Directed self-organization and Molecular wiring of catalytic nanoparticles for fuel cells

Dutta N.K., Mayavan S., Roy Choudhury N., University of South Australia, AU

The usefulness of nanosized metallic particles in new generation devices and materials has prompted researchers to synthesize particles on various novel supports. The tunability in size and distribution of nanoparticles via bottom up tools opens [...]

Modeling the Temperature Field in Reforming Anodes of a Button-Shaped SOFC

Zinovik I., Poulikakos D., ETH Swiss Federal Institute of Technology, CH

A new model for the determination of the temperature field in porous reforming anodes of SOFCs is presented. The model is implemented in a commercial CFD software package. Heat transfer, fluid flow and electrochemical reactions [...]

Effects of Spin Coating Catalysts on Micro-Fuel Cells Efficiency

Lung T., Reissman T., Kirby B., Garcia E., Cornell University, US

Using spin coating as the catalyst application technique in order to receive an even distribution on the porous silicon PEM. With even distribution, resistivity is more consistent, which produces a better power output from the [...]

Continuous Hydrothermal Flow Syntheses of Nanosize Materials Used In Solid Oxide Fuel Cells

Weng X., Darr J.A., University College London, UK

Our research group has developed a novel nanomaterials synthesis method using a continuous hydrothermal flow synthesis (CHFS) reactor. In this reactor, nanosize particles are produced through co-precipitation in supercritical water. Sub 50 nm sized particles [...]

In-plane and through-plane electrochemical conductivity and fuel cell performance of thin-film YSZ electrolytes

Johnson A.C., Ramanathan S., Harvard University, US

Submicron electrolyte films are a key component of intermediate temperature solid oxide fuel cells. Several groups have reported size-dependent in-plane ionic conductivity in thin films of yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria. Here we report [...]

FTC’s Regulation of Green Marketing Claims

Laws E.P., Leopold C.B., PillsburyWinthrop Shaw Pittman LLP, US

Over the past several years, issues of climate change and sustainability have gained increasing prominence in the minds of the public; and, as a consequence, consumers have demanded greater access to “greener” products and services. [...]

Institutional Challenges and Opportunities: Decentralized and Integrated Water Resource Infrastructure

Nelson V.I., Coalition for Alternative Wastewater Treatment, US

The failure of mainstream water and wastewater utilities to adopt decentralized technologies can be attributed to institutional and market barriers. The framework of policies and markets need to be altered and expanded to include: integrated [...]

Public Policy and Cleantech – Obstacle or Asset?

Wardak A., Taneja V., University of Virginia, US

Alongside the development, commercialization, and entrance of clean technologies (i.e. cleantech) into mainstream North American markets, has been the North America investment community, which has made great strides to support cleantech innovations.

Environmental Performance Assessment of Companies: Applying Life Cycle Assessment at the Enterprise Level

Dettling J., Loerincik Y., Margni M., Jolliet O., Ecointesys - Life Cycle Systems, US

Sustainability is rapidly increasing in emphasis among the world’s leading companies. There is increasing pressures on companies to understand and be able to communicate the impacts of their products and activities. This pressure comes internally-from [...]
