Experimental characterization of a solid oxide fuel cell coupled to a steam-driven micro anode off-gas recirculation fan

Jan Van Herle, Jürg Alexander Schiffmann, Stefan Diethelm, Zacharie Wuillemin, Patrick Hubert Wagner, David Constantin

While the global fuel utilization of solid oxide fuel cells (SOFCs) is limited by the stack aging rate, the fuel excess is typically used in a burner, and thus limiting the system electrical efficiency. Further, natural-gas-fueled SOFCs require treated wat ...

Methodology for the design and comparison of optimal production configurations of first and first and second generation ethanol with power

François Maréchal, Rami Bechara, Jean-Marc Schweitzer

This article applies a systematic methodology to the optimization and comparison of two sugarcane conversion processes of great potential: the production of first generation ethanol and electricity in an integrated distillery and cogeneration plant (1G+COG ...

Optimisation of unit investment and load shedding in a steam network facing undercapacity

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener

Steam networks and their utilities should be dimensioned to satisfy day-to-day demand as well peaks. Peaks can be caused by unit start-ups, extreme weather conditions or combinations of high demand from process units. During maintenance operations or unexp ...

Some methods of dynamic nuclear polarization for use in metabolic imaging

Fiodar Kurdzesau

It has been suggested already more than 60 years ago to use polarized nuclei in particle scattering experiments1, but only with the discovery of the solid effect dynamic nuclear polarization process2 the realisation of polarized solid targets became possib ...
