Formation Mechanisms and Structural Properties of Aluminium-Chromium Based Oxynitride Thin Films Synthesized by Physical Vapor Deposition

Hossein Najafi

Oxynitride thin films, a novel class of mixed anionic solid structures, have gained an intense interest during recent years related to the unique interplay of oxygen (O) and nitrogen (N) with metals in the material structure. This matter can result in spec ...

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 ...

Plasma Spray-CVD: A New Thermal Spray Process to Produce Thin Films from Liquid or Gaseous Precursors

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

New dedicated coating processes which are based on the well-known LPPS (TM) technology but operating at lower work pressure (100 Pa) are being actively developed. These hybrid technologies contribute to improve the efficiencies in the turbine industry such ...

Air Side Contamination in SOFC Stack Testing

Jan Van Herle, Christian Ludwig, Zacharie Wuillemin, Josef Andreas Schuler, Christian Gehrig

2010

, ,

Structural reliability is a hurdle for the large-scale commercialisation of solid oxide fuel cell (SOFC). The cells are prone to cracking, due to the brittleness of their constitutive materials. In operation, the failure of one of them can arise from the n ...

Self and induced stabilized nanoparticles for electrocatalysis

Mériadec Limat

Since few decades the search of new catalysts formulations for fuel cell applications has motivated numerous projects especially due to the future lack of fossil fuel, environmental and economical reasons. Consequently, Direct Alcohol Fuel Cell (DAFC) or D ...

Microfabricated solid oxide fuel cells

Samuel Rey-Mermet

Micro-fabricated solid oxide fuel cells (µSOFCs) are finding an increasing interest as potential power sources for portable devices such as MP3 players or laptops. The aim of this work was to fabricate a µSOFC demonstrator that works at 500°C and is fuelle ...

Quantitative study of Ni-zirconia anode micro- and nanostructure 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 mechanisms in order to find solutio ...
