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 ...

Influence of Operational Parameters on LSCF and LSF Stability

Jan Van Herle

(La0.6Sr0.4)0.95FeO3-δ/ Sm0.2Ce0.8O2 (70:30 w/w) and (La0.6Sr0.4)0.995Co0.2Fe 0.8O3-δ/Gd0.1Ce0.9O 2 (50:50 w/w) cathodes screen printed on anode-supported cells were tested for 500 h under different conditions by using a Taguchi matrix that combined cathod ...

Demand Response Using Service Curves

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We propose an alternative approach, based on ``service curves", which uses the following two ingredients. (1) The rate at which a consumer may draw power from the grid may be controlled by real time signals. Typical concerned devices would be heating syste ...

Demand Response Using Service Curves

Jean-Yves Le Boudec, Dan-Cristian Tomozei

Existing methods for demand response either assume direct control of appliances by supplier, or assume that consumers adapt their load by reacting to pricing signals. The former are intrusive and might not scale well; the latter expose consumers to price v ...

Mitigating Cr Contamination by Hot Air Filtering in Solid Oxide Fuel Cells

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

Cr contamination, generated by system components located upstream a solid oxide fuel cell (SOFC) and responsible for Cr-poisoning induced air electrode performance degradation, must be suppressed by hindering the access of Cr pollutants to the cathode comp ...

Air-water two-phase flow approach to simulate nearshore wave motion

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

The two-dimensional two-phase Navier-Stokes equations, volume of fluid technique and a two-equation turbulence closure model were used to predict wave breaking and runup, and compared with experimental data. Comparison of the results with a corresponding s ...

Stream temperature modeling using fiber optic distributed temperature measurements in a sub-Saharan watershed, Burkina Faso

Malik Matthey

High spatial and temporal resolution water temperature measurements, using DTS, allow to model and to control stream temperature evolution in the Tambarga’s basin (Burkina Faso). A wireless sensor network recorded solar radiation, air temperature, air humi ...

Prototype of a thermally driven heat pump based on integrated organic Rankine cycles (ORC)

Daniel Favrat, Samuel Henchoz, Jonathan Demierre

The concept studied in this work is a low power ORC-ORC system (about 20 kW heat at the condenser) which is composed of an ORC engine cycle driving a reversed ORC heat pump cycle, both using the same fluid. The radial compressor and turbine are directly co ...
