Quantitative study of anode microstructure related to SOFC stack degradation

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

As the performances of Solid Oxide Fuel Cells (SOFC) get attractive, long term degradation becomes the main issue for this technology. Therefore it is essential to localise the origin of degradation and to understand its processes in order to find solution ...

Qualitative evaluation of alkali release during the pyrolysis of biomass

Christian Ludwig, Alexander Wokaun

The thermochemical emission of alkali metals from biomass samples and two organic salts was investigated for the first time using a novel combination of a th ermogravi metric analyzer with a jet flow condenser attached to a surface ionization detector. Thi ...

Methodology for the optimal thermo-economic, multi-objective design of thermochemical fuel production from biomass

François Maréchal, Martin Gassner

This paper addresses a methodology for the optimal conceptual design of thermochemical fuel production processes from biomass. A decomposed modelling approach with separate energy-flow, energy-integration and economic models is presented and coupled to mul ...

A 300 W solar chemical pilot plant for the carbothermic production of zinc

Aldo Steinfeld

In the framework of the EU-project SOLZINC, a 300-kW solar chemical pilot plant for the production of zinc by carbothermic reduction of ZnO was experimentally demonstrated in a beam-down solar tower concentrating facility of Cassegrain optical configuratio ...

Electrochemical promotion of Pt catalysts for gas phase reactions

Arnaud Jaccoud

The subject of this work is the study of the electrochemical promotion of catalysis (EPOC), also called non-Faradaic electrochemical modification of catalytic activity (NEMCA). In this phenomenon, application of small currents or potentials on catalysts in ...

Hydrogenation of C60 at 2GPa pressure and high temperature

Yury Tsybin

Hydrogenation of C60 at 2 GPa and 723-823 K was performed with thermal decompn. of LiAlH4 as a hydrogen source. Anal. of hydrogenation products showed that the method can produce not only C60H36, but also hydrofullerides C60Hx with 44 < x < 52. Unlike othe ...

A phenomenological model for macroscopic deactivation of surface processes

Christos Comninellis, Hannes Bleuler, Rolf Wüthrich

There is a wide class of electrochemical systems which present a sudden transition from a high to a low reaction rate region in function of an external parameter. This sudden transition is accompanied by the growth of a surface structure responsible for de ...

Conductivity of Mn and Ni-doped stabilized zirconia electrolyte

Jan Van Herle

We develop SOFC based on a NiO–YSZ anode support, a thin YSZ layer (5–10 micron) and a LaSrMnO3 cathode. Mn and Ni can dissolve into thin zirconia during high temperature fabrication. On cells, we consistently measured higher ohmic losses than expected fro ...
