Methods for quantification of anode support microstructure

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Christian Monachon

Degradation observed on long term stack tests may be explained in part by microstructural changes of the electrodes. Particularly at the anode side, the coarsening of nickel particles will affect its performances. Increasing the metal particle size will fi ...

Anode dusting during the electrolytic production of aluminium

Timea Tordai

The disintegration of the carbon anodes during the electrolysis of alumina produces dust particles contaminating the electrolytic bath. This phenomenon, called dusting, is one of the most deleterious Al electrolysis failures, as it leads to a significant d ...

Electrochemical generation of Cu(I) complexes in aqueous solutions studied by on-line mass spectrometry

Hubert Girault, Christophe Roussel, Michel Prudent

Taking advantage of the electrochemical aspects of electrospray ionization (ESI) sources in positive ionization mode mass spectrometry (MS), aqueous copper complexes are electrogenerated using sacrificial copper electrodes. When using 8-hydroxyquinoline or ...

Catalytic steam reforming of methane over La0.8Sr0.2CrO3 based Ru catalysts

Cyril Cayron

La0.8Sr0.2CrO3 based Ru catalysts were studied as potential new anodic materials for Solid Oxide Fuel Cells directly fed with methane and operating at intermediate temperature under water deficient conditions. Two kinds of materials very close in compositi ...

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 ...

OptoMEA: a new tool for combining local optical activation of compounds with distributed MEA recordings

Diego Ghezzi, Marc Olivier Heuschkel, Solomzi Makohliso

Since their introduction, Micro-Electrode Arrays (MEAs) have been exploited as devices providing distributed information about learning, memory and information processing in a cultured neuronal network, thus changing the field of view from single cell leve ...

Transport phenomena in nanofluidics

Reto Bruno Schoch

This thesis explores transport phenomena in nanochannels on a chip. Fundamental nanofluidic ionic studies form the basis for novel separation and preconcentration applications for proteomic purposes. The measurements were performed with 50-nm-high 1D nanoc ...

Préparation et caractérisation de nanoparticules bimétalliques (Pt-Au) sur un substrat en diamant dopé au bore

Bahaa El Roustom

Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...

REVERSE TRANSFER OF NANOSTENCIL PATTERNS USING INTERMEDIATE SACRIFICIAL LAYER AND LIFT-OFF

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

We have developed a new process for reversing the nanostencil patterns by using an intermediate sacrificial layer. Using this process, we can pattern isolated ‘empty’ shapes with their background filled with a certain material, which is impossible with the ...

Simulation of SOFC stack and repeat elements including interconnect degradation and anode reoxidation risk

Daniel Favrat, Jan Van Herle, Diego Larrain

Reliability of SOFC stacks is a complex and key issue. This paper presents a simulation study including some degradation processes, namely, interconnect degradation and the anode reoxidation potential. Quantification for these phenomena has been included i ...
