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 [...]

A Versatile Nanofabrication Technology for Polymer / Inorganic Composites for Fuel Cell and Pulse Power Applications

Lee S., Breitkopf R., Hwang J., Faguy P., Hunt A., MicroCoating Technologies, Inc., US

An innovative atomizer, capable of producing sub-micron size droplets, in conjunction with Combustion Chemical Vapor Deposition (CCVD), a flame based technique have demonstrated the capability to produce nanoscale hybrid materials with morphological, compositional and internal [...]

Influence of the Microstructure of the Catalyst Layer on the Performance of the PEMFC Cathode

Fontes E., Schumacher J., Vasileiades N., Parhammar O., Schmitz A., COMSOL Inc., US

This paper presents a model of a unit cell of a PEMFC for applications in portable electronic devices. The model introduces the transport resistance exerted by the electrolyte confined in the active layer using a [...]

The Electroreduction of Hydrogen on Pt(111)

Marzari N., Blum L., Car R., University of Puerto Rico, US

The electroreduction of hydrogen on Pt(111) in acidic media is the primary fuel cell reaction. The explicit mechanism for this process involves a first order phase transition, which is due to the rotation of the [...]
