This paper presents the optimal design and operation of a micro power generation process that consists of a reactor, a solid-oxide fuel cell (SOFC) and two burners in a stack fed with ammonia and butane fuels. Hydrogen is produced from ammonia decompositio ...
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 ...
The aim of this project was to develop and implement an optimisation methodology that combines process thermo-modelling and process integration in a thermo-economic optimisation framework for fuel cells systems. During this project, a generic software has ...
A general procedure based on the oxalate coprecipitation route was developed to produce very sinterable ceria (CeO2) powder doped with Gd2O3, Sm2O3 or Y2O3. The method is simple, reliable and very reproducible. Without any milling step, powder of 20 mol% G ...
Solid oxide fuel cell (SOFC) stacks are extremely vulnerable to mechanical failures in any of their constituents, which ultimately lead to cell cracking. Like all devices, distinct failure sequences arise from different events or design particularities. Th ...
We optimize the preparation of BZY20 and BCY10 by a wet chemistry route (the polyacrylamide gel process) and mixed oxide route, respectively. For both materials, the purity of powders drastically depends on the annealing conditions of the raw materials. Pu ...
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 ...
