Solid Oxide Fuel Cells (SOFCs) have gathered considerable attention as a clean, highly efficient conversion device for the production of both electricity and heat from fuels. Due to their high operating temperatures, SOFCs do not require pure hydrogen as f ...
During millions of years of evolution, all creatures have found their ways of harvesting, storing and utilizing the energy coming from the sun. Plants use photosynthesis to convert carbon dioxide to glucose. With a low efficiency of only 3%, plants still c ...
Here we show preparation and characterization of a new type of composite membrane based on Nafion (R)/histidine modified carbon nanotube by imidazole groups (Im-CNT), for direct methanol fuel cell (DMFC) applications. Due to the presence of this imidazole- ...
Here we describe preparation and characterization of a series of nanocomposite polyelectrolytes based on partially sulfonated poly (ether ether ketone) (SPEEK) and organically modified montmorillonite (MMT). Optimum degree of sulfonation for SPEEK is selec ...
Switzerland has a small but internationally recognised set of competences and actors in fuel cells and hydrogen, from fundamental research to technology and product development. Swiss organisations are prominent in a number of research partnerships, and so ...
Three Ta-based compds. were successfully prepd. using a simple chem. synthesis. In dye-sensitized solar cell systems Ta3N5, TaOx, and Ta4C3 acted as counter electrode catalysts and demonstrated impressive catalytic activity and stability for I3- redn. The ...
With regard to sustainability it is often referred to the “Hydrogen Economy” as an alternative to cover the energy needs by using hydrogen as a fuel source. The goal of this project is to study the production of hydrogen by using the formic acid decomposit ...
The surface morphology of MnSi thin films grown on Si(111)-7 x 7 substrates was investigated by systematically changing the amount of deposited Mn. A new 3 x 3 surface reconstruction was found at the very initial growth stages, whose atomic configuration w ...
Some fundamental challenges are shaping the world we live in, and the need for alternative materials and energies is one of the most prominent issues of this century, especially in the light of global warming and energy need. Another crucial point concerns ...
We introduce a paradigm-"hydricity"-that involves the coproduction of hydrogen and electricity from solar thermal energy and their judicious use to enable a sustainable economy. We identify and implement synergistic integrations while improving each of the ...
