Simulation of thermal stresses in anode-supported solid oxide fuel cell stacks. Part I: Probability of failure of the cells

Daniel Favrat, Jan Van Herle, Zacharie Wuillemin, Arata Nakajo

Structural stability issues in planar solid oxide fuel cells arise from the mismatch between the coefficients of thermal expansion of the components. The stress state at operating temperature is the superposition of several contributions, which differ depe ...

Surface oxide in replicated microcellular aluminium and its influence on the plasticity size effect

Andreas Mortensen, Frédéric Diologent

The oxide film present along the interface between metal and pores in microcellular aluminium produced by replication depends on the leaching medium that is used to dissolve the NaCl preform: leaching in water produces a thick and irregular multilayered hy ...

About the Electrospray Ionization Source in Mass Spectrometry: Electrochemistry and On-chip Reactions

Hubert Girault, Niels Erik Lion, Christophe Roussel, Manuel Alejandro Méndez Agudelo, Michel Prudent, Joël Stéphane Rossier, Bin Su

The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...

Effect of electrode potential on the tribocorrosion of tungsten

Michel Declercq, Didier Bouvet, Stefano Mischler, Jelena Stojadinovic

The tribocorrosion behavior of tungsten sliding against an alumina ball was evaluated in sulfuric acid under applied electrode potential. Surface chemistry of worn and unworn surfaces was evaluated using XPS and AES. Quasi-potentiostatic polarization curve ...

Solid oxide fuel cell redox instability characterized by in situ transmission electron microscopy

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

A solid oxide fuel (SOFC) cogenerates heat and electricity with high efficiency. Electricity is produced by the electrochemical reaction of a fuel (H2, CO, CH4) and an oxidant gas (O2, air). The SOFC standard design is based on an anode-supported electroly ...

Structural and electronic implications for carrier injection into organic semiconductors

Philippe Bugnon, Mauro Castellani

We report on the structural and electronic interface formation between ITO (indium-tin-oxide) and prototypical organic small molecular semiconductors, i.e., CuPc (copper phthalocyanine) and alpha-NPD (N,N'-di(naphtalen-1-yl)-N,N'-diphenyl-benzidine). In pa ...

Redox study of anode supported solid oxide fuel cell

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

The common technology for solid oxide fuel cells (SOFC) is based on a cermet anode of nickel with yttrium stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this anode technology is the redox tolerance. In thi ...

A new strategy of molecular overcharge protection shuttles for lithium ion batteries

Michael Graetzel, Shaik Mohammed Zakeeruddin

The conventional strategy of overcharge protection for lithium ion batteries uses redox molecules having oxidation potential higher than the cathodic materials in the electrolyte. Here we propose a novel approach by using redox molecules having reduction p ...

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 ...
