Investigation of the Pt/YSZ interface at low oxygen partial pressure by solid electrochemical mass spectroscopy under high vacuum conditions

Christos Comninellis, Wolfgang Harbich, György Foti, Cyril Falgairette, Chun Xia

The Pt/YSZ interface was investigated at low oxygen partial pressure under high vacuum (HV) conditions at 400 A degrees C. Two different electrochemical techniques were coupled to mass spectrometric gas analysis using a new solid electrochemical mass spect ...

In situ redox cycle of a nickel-YSZ fuel cell anode in an environmental transmission electron microscope

Jan Van Herle, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Antonin Faes, Ulrich Aschauer

Environmental transmission electron microscopy is used in combination with density functional theory calculations to study the redox stability of a nickel/yttria-stabilized zirconia solid oxide fuel cell anode. The results reveal that the transfer of oxyge ...

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, ...

RedOx study of anode supported solid oxide fuel cell

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Arata Nakajo, David Dubois

The common technology for solid oxide fuel cells (SOFC) is based on a cermet (ceramic-metal composite) anode of nickel with yttria stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this technology is the tole ...

In situ Reduction and Oxidation of Nickel from Solid Oxide Fuel Cells in a Transmission Electron Microscope

Jan Van Herle, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Antonin Faes

Environmental transmission electron microscopy was used to characterize in situ the reduction and oxidation of nickel from a Ni/YSZ solid oxide fuel cell anode support between 300-500°C. The reduction is done under low hydrogen pressure. The reduction init ...

Sulfur as Pollutant Species on the Cathode Side of a SOFC System

Jan Van Herle, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler

In order to link electrochemical performance degradation of the cathode in a large solid oxide fuel cell (SOFC) to the presence of pollutant species, a spatially-resolved study of contaminants was performed. Distribution maps of pollutants over the cell al ...
