Fuels for Fuel Cells : Requirements and Fuel Processing

Polymer electrolyte and solid oxide are the two fuel cell types (PEFC, SOFC) under development in Switzerland. The very distinct operating temperatures of 80 °C (PEFC) and 800–950 °C (SOFC) impose fundamentally different requirements upon the nature of the ...

Comment on "greenland-Antarctic phase relations and millennial time-scale climate fluctuations in the Greenland ice-cores" by C. Wunsch

Jérôme Chappellaz, Daniele Romanini

Ancient air trapped inside bubbles in ice cores can now be analysed for methane concentration utilising a laser spectrometer coupled to a continuous melter system. We present a new ultra-high resolution record of atmospheric methane variability over the la ...

Energy balance model of a SOFC cogenerator operated with biogas

François Maréchal, Daniel Favrat, Jan Van Herle

A small cogeneration system based on a Solid Oxide Fuel Cell (SOFC) fed on the renewable energy source biogas is presented. An existing farm biogas production site (35 m3 per day), currently equipped with a SOFC demonstration stack, is taken for reference. ...

Biogas exploitation by SOFC

Daniel Favrat, Jan Van Herle

Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...

Lean-Burn Cogeneration Biogas Engine with Unscavenged Combustion Prechamber: Comparison with Natural Gas

Daniel Favrat, Roger Röthlisberger

Gaseous fuels produced, for example, by waste or agricultural by-products fermentation (biogas) can be burned in-situ by cogeneration systems like spark- ignition internal combustion engines. However, the more and more stringent legislation for exhaust gas ...

Materials for Methane-fueled SOFC Systems

Jan Van Herle, Stefan Diethelm, Raphaël Ihringer, Joseph Sfeir

Abstract: A short overview of recent work on electroceramic materials relevant to methane-fueled SOFC systems is given. Various fuel feed options are considered, such as pure methane, biogas, and the addition of reforming agents. The principle and implemen ...
