A micro heater platform with fluid channels for testing micro-solid oxide fuel cell components

Paul Muralt, Thomas Maeder, Bo Jiang, Dimos Poulikakos

Micro-scale solid oxide fuel cell is a promising power generation technology for portable devices such as laptop, medical devices and personal electronics. One of the key goals in design of μ-SOFC systems is to use common hydrocarbon fuels such as propane/ ...

Air Side Contamination in Solid Oxide Fuel Cell Stack Testing

Jan Van Herle, Christian Ludwig, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler, Christian Gehrig

Solid Oxide Fuel Cells (SOFCs) are likely candidates for electricity production with high efficiency and promise reasonable fuel tolerance. While fuel impurities are known anode poisons, less attention is brought to air-purity, especially to air-side conta ...

Intégration énergétique d’un procédé agroalimentaire à l’aide de la plateforme internet PinchLight

Benjamin Laulan

Résumé : Les procédés agroalimentaires sont des procédés industriels consommateurs de grandes quantités d’énergie, aussi bien de refroidissement que de chauffage. Il est donc intéressant d’optimiser cette consommation. L’analyse pinch, méthode systématique ...

Impact of Trust Management and Information Sharing to Adversarial Cost in Ranking Systems

Karl Aberer

Ranking systems such as those in product comparison sites and recommender systems usually use ratings to rank favorite items based on both their quality and popularity. Since higher ranked items are more likely selected and yield more revenues for their ow ...

Experimental and modeling investigations on local performance and local degradation in solid oxide fuel cells

Zacharie Wuillemin

This thesis focuses on performance, reliability and degradation in solid oxide fuel cells (SOFC), which currently represent the three key technical challenges for the deployment of this technology. By its development of dedicated modeling and experimental ...

, , ,

A solid oxide fuel (SOFC) cogenerates heat and electricity with high efficiency. Electricity is produced by the electrochemical reaction of a fuel (H2, CO, CH4) and an oxidant gas (O2, air). The SOFC standard design is based on an anode-supported electroly ...
