Recent Advances in Electrospun Fiber Mat Electrode MEAs for Hydrogen/Air Fuel Cells

Waldrop K., Fan X., Kang N., Wycisk R., Gumeci C., Dale N., Pintauro P.N., Vanderbilt University, US

The hydrogen/air proton-exchange membrane fuel cell is a promising candidate for automotive power plants, but Pt/C catalyst electrode cost and durability are still issues that require further study. Recently, there has been considerable work on [...]

Creating a Global Hydrogen Infrastructure from Waste Materials

Madden D., Eco Energy International, LLC, US

The lack of a hydrogen infrastructure has impeded the implementation of fuel cell technology in many areas worldwide. At the same time, the world is awash with waste materials. For example, Municipal Solid Waste (MSW) [...]

A novel approach towards PGM-free PEM fuel cell cathodes

Anson C., Gerken J., Preger Y., Biswas S., Root T., Stahl S., University of Wisconsin-Madison, US

One of the major obstacles preventing widespread implementation of PEM fuel cells is the current requirement for prohibitive loadings of Pt at the cathode to achieve high activity for the oxygen reduction reaction. The Pt [...]

Why Hydrogen?

Blanchet S., Nuvera Fuel Cells, US

Modern civilization has grown reliant on plentiful, cheap and convenient energy from fossil fuels. Now, the reality of climate change has compelled us to reconsider our current ways of producing and using energy. The standardization [...]

Bimetallic Nanoparticles for Advanced Energy Conversion Technologies

Sims C.M., Eichhorn B.W., University of Maryland, US

Proton exchange membrane fuel cells (PEMFC) are highly regarded as a clean alternative energy technology for motor vehicles, power generators, etc. One factor hindering their commercial viability is the poisoning of the hydrogen oxidation reaction [...]

Properties of xYSZ nanoparticles and pellets with x varying from 1 to 15%

Suciu C., Dorolti E., Hoffmann A.C., University of Bergen, NO

Nanoparticles of oxides are used, among other things, for solid oxide fuel cells (SOFCs), where the use of yttria-stabilized zirconina nanoparticles in the inner region of the anode will increase the extent of the "triple-phase [...]
