After 10,000 h solid oxide fuel cell (SOFC) stack operation, the Cr-poisoning situation in (La0.6Sr0.4) (Co0.2Fe0.8)O-3 (LSCF)-based cathode material is depicted in this work. Systematic Cr profiling by energy-dispersive X-ray spectroscopy (EDS), from post ...

Energy-filtered transmission electron microscopy images are acquired during the reduction of a NiO-YSZ composite in H-2 up to 600 degrees C. Temperature-resolved quantitative information about both chemistry and structure is extracted with nm spatial resol ...

L’objectif du travail entrepris est de développer un outil permettant la simulation dynamique d’un syteème de pile à combustible à haute température (SOFC). Des modèles génériques ont été développés afin de pouvoir représenter les différents composants du système tels que stack, reformeur échangeurs de chaleur, etc. Une configuration d’un système SOFC de 250W électriques (qui constitue la taille d’un prototype de démonstration en élaboration au laboratoire) est présentée, alimenté à titre d’exemple en bioga

A 3D simulation tool for solid oxide fuel cells is presented. The aim of this work is to predict current density, flow, temperature and concentration fields in order to compare and optimize repeat element geometry for a whole stack. A commercial CFD tool w ...

Le but de cette étude est de comparer la microstructure de l’anode en fonction des conditions de réduction et lors de cycles redox. Pour réaliser ce projet, un code Mathematica® est développé. Celui-ci permet de traiter et d’analyser des images SEM pour en extraire la proportion des différentes phases, leur taille de grain et leur contiguïté.
