Sulfur as pollutant species on the cathode side of a SOFC system

Aïcha Hessler-Wyser

Sulfur poisoning in a strontium doped lanthanum cobaltite (LSC) cathode current collection layer was revealed in a solid oxide fuel cell (SOFC) tested in repeat-element and stack configuration. Sources of sulfur contamination, other than trace SOx in air, ...

Development of micromorph tandem soalr cells on flexible low cost plastic substrates

Christophe Ballif, Franz-Josef Haug, Xavier Niquille, Vanessa Terrazzoni-Daudrix, Thomas Söderström, Martin Python

We report on the development of fully flexible microcrystalline and micromorph tandem solar cells directly on low-cost substrates like poly-ethylen-terephtalate (PET) and poly-ethylen-naphtalate (PEN). The cells are deposited in nip or nip/nip configuratio ...

Electrical modeling of the cell-electrode interface for recording neural activity from high-density microelectrode arrays

Alexandre Schmid, Yusuf Leblebici, Neil Joye

Accurate electrical models are needed to support the design of modern microelectrode arrays. The point-contact model is presented thoroughly, and an area-contact model is analytically derived in order to model the electrical characteristics of the cell-ele ...

Modeling of Local Cell Degradation in Solid Oxide Fuel Cells: Cumulative Effect of Critical Operating Points

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Antonin Faes, Zacharie Wuillemin, Arata Nakajo, Nordahl Autissier

A CFD model was developed to predict with accuracy the local electrochemical performance in an operating solid oxide fuel cell. A particular focus was given on the study of performance limitations and degradation sources caused by the design of the fuel ce ...

Bloch wave approach to the design of optimally matched non-effective medium composite right/left handed transmission lines

Anja Skrivervik, Julien Perruisseau-Carrier

A simple method to design optimally matched composite right-/left-handed transmission lines (CRLH-TLs), based on the computation of the Bloch wave equivalent impedance of the corresponding unit cell circuit is presented. Although the matching of CRLH-TLs t ...

Compact 100 W stacks using thin components of anode supported cells and metal interconnects

Jan Van Herle, Raphaël Ihringer, Nicolas Badel, Nordahl Autissier, Diego Larrain, Joseph Sfeir

Progress on anode supported cell stacks (SOFCONNEX design, 50 m2 per cell) is presented. A 6-cell stack and a 8 cell-stack were mounted and tested with hydrogen fuel at 800 degre C, yielding 100 W el and 140 W el, corresponding to a power density of 1kW el ...

Biosystem for the culture and electrical characterisation of epithelial cell tissues

Serge Hediger

The aim of this work was to develop a microchamber system for performing electrophysiological measurements on epithelial surface on culture membranes in the mm2 range. This miniaturised system permits the use of small quantities of epithelial cells, which ...
