Solid Oxide Fuel Cell (SOFC) application development is very well represented in Switzerland by two companies. Sulzer Hexis AG is one of the world leaders in the commercialization of SOFC systems for single family houses. A smaller company, HTceramix, is a ...
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 ...
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 ...
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 ...
LENI activities in SOFC are focused on development of a new planar stack concept based on anode supported cells in collaboration with the company HTceramix SA. Modeling of repeat element, stack and systems is starting in parallel. This work presents a mode ...
We develop SOFC based on a NiO–YSZ anode support, a thin YSZ layer (5–10 micron) and a LaSrMnO3 cathode. Mn and Ni can dissolve into thin zirconia during high temperature fabrication. On cells, we consistently measured higher ohmic losses than expected fro ...
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 ...
