Journal ArticleDOI
Simulation of thermal stresses in anode-supported solid oxide fuel cell stacks. Part I: Probability of failure of the cells
TL;DR: In this paper, the authors used a finite-element software (ABAQUS) to calculate the distribution of stress and contact pressure on all components of a standard solid oxide fuel cell repeat unit, i.e., anode, electrolyte, cathode and compensating layer.
Simulation of thermal stresses in anode-supported solid oxide fuel cell stacks
TL;DR: In this article, the authors used the Weibull analysis to evaluate the structural stability of planar solid oxide fuel cells (SOFC) in both steady-state and dynamic operations.
Journal ArticleDOI
Modeling of thermal stresses and probability of survival of tubular SOFC
TL;DR: In this article, the thermal stress distribution in a tubular solid oxide fuel cell (SOFC) was calculated separately for each layer of the MEA (membrane electrode assembly) in order to detect the radial thermal gradients more precisely.
Journal ArticleDOI
RedOx study of anode-supported solid oxide fuel cell
Antonin Faes,Arata Nakajo,Aïcha Hessler-Wyser,David Dubois,Annabelle Brisse,Stefano Modena,Jan Van herle +6 more
TL;DR: In this paper, two techniques are used to quantify the anode expansion after one redox cycle at different temperatures: the increase of porosity is measured using scanning electron microscopy (SEM) image quantification, and the second method considers the expansion above the electrolyte fracture limit by measuring the crack width in the electrolytes layer.
Journal ArticleDOI
Compilation of mechanical properties for the structural analysis of solid oxide fuel cell stacks. Constitutive materials of anode-supported cells
Arata Nakajo,Arata Nakajo,Jakob Kuebler,Antonin Faes,Ulrich Vogt,Hans J. Schindler,Lieh-Kwang Chiang,Stefano Modena,Jan Van herle,Thomas Hocker +9 more
TL;DR: In this article, the mechanical properties of anode-supported solid oxide fuel cell (SOFC) stacks are analyzed for the simulation of stresses, with an emphasis on temperature and porosity dependence and the evolution upon aging or cycling when available.
