Journal ArticleDOI
Evolution of the electrochemical interface in high-temperature fuel cells and electrolysers
John T. S. Irvine,Dragos Neagu,Maarten C. Verbraeken,Christodoulos Chatzichristodoulou,Christopher R. Graves,Mogens Bjerg Mogensen +5 more
TL;DR: In this paper, the authors review the evolution of the interface under operation, highlighting approaches to control and improve interfacial architectures and cell performance, and explore the new chemistries that allow control and manipulation of these architectures to optimize both performance and durability.
Journal ArticleDOI
Chemical Expansion: Implications for Electrochemical Energy Storage and Conversion Devices
Sean R. Bishop,Sean R. Bishop,Dario Marrocchelli,Dario Marrocchelli,Christodoulos Chatzichristodoulou,Nicola H. Perry,Mogens Bjerg Mogensen,Harry L. Tuller,Harry L. Tuller,Eric D. Wachsman +9 more
TL;DR: A taxonomy of chemical expansion can be found in this paper, along with an overview of factors impacting chemical expansion, as well as a discussion of its implications for mechanical stability and functionality in the energy applications above and in other oxide-based systems.
Journal ArticleDOI
Size of oxide vacancies in fluorite and perovskite structured oxides
TL;DR: In this article, an analysis of the effective radii of vacancies and the stoichiometric expansion coefficient is performed on metal oxides with fluorite and perovskite structures, and the results show that the effective radius of an oxide vacancy in doped LaGaO3 is only about 6% smaller than the oxide ion.
Journal ArticleDOI
Enhanced mass diffusion phenomena in highly defective doped ceria
Vincenzo Esposito,De Wei Ni,Zeming He,Wei Zhang,Aditya Prasad,Julie Glasscock,Christodoulos Chatzichristodoulou,Severine Ramousse,Andreas Kaiser +8 more
TL;DR: In this paper, the densification and grain growth of the solid state ionic conductor material Ce 0.9 Gd 0.1 O 1.95− δ (i.e., GDC10, gadolinium-doped ceria, with Gd 10.
Journal ArticleDOI
Understanding degradation of solid oxide electrolysis cells through modeling of electrochemical potential profiles
Christodoulos Chatzichristodoulou,Ming Chen,Peter Vang Hendriksen,Torben Jacobsen,Mogens Bjerg Mogensen +4 more
TL;DR: In this article, the spatial distribution of the various chemical and electrochemical potentials in an operating SOEC is established on the basis of a two dimensional bi-layer electrolyte SOC model including for both electrodes a description of activation, concentration, and conversion losses.
