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 ...

Equilibrium island-size distribution in one dimension

Klaus Kern, Harald Brune, Pietro Gambardella

We derive an analytical expression for the size distribution of monoatomic wires in the framework of a one-dimensional lattice gas model at thermodynamic equilibrium. The theoretical results are compared with the size distribution of one-dimensional Ag wir ...

Evidence for a diffusion-based mechanism of liquid metal intergranular penetration : case study of a Ni-Bi model system

Vincent Laporte

A model Ni-Bi system has been used to investigate intergranular penetration (IGP) phenomenon. All experiments have been done on Ni 26° bicrystal at 700°C using bismuth vapour condensation as a source of liquid bismuth. Such a procedure results at room ...

Multi-scale modeling methodology for computer aided design of a Solid Oxide fuel cell stack

François Maréchal, Daniel Favrat, Jan Van Herle, Nordahl Autissier, Diego Larrain

This paper presents the modeling strategy developed for the design of a planar solid oxide fuel cell repeat element. Design goal are to reach good performance (power density) and reliability (ie. limit risk of failure and degradation). This challenging pro ...

In thermodynamic equilibrium with sea water the Sr/Ca ratio of aragonite varies predictably with temperature and the Sr/Ca ratio in coral have thus become a frequently used proxy for past Sea Surface Temperature (SST). However, biological effects can offse ...
