Basil Duval, Umar Sheikh, Gergely Papp
Disruption mitigation remains a critical and unresolved issue for ITER. Measurement uncertainties preventing quantification of a system's efficacy remains a significant hurdle in producing and validating a viable disruption mitigation system. This study ad ...
2020Thermochromic solar absorber coatings with elevated transition temperature
Due to their simple design and operation, solar thermal collectors for domestic hot water gener-ation and space heating are one of the most common solar energy harvesting systems in use today. Dur-ing cold periods all the absorbed energy is useful. During ...
EPFL2020Model-assisted identification of solid oxide cell elementary processes by electrochemical impedance spectroscopy measurements
Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro
Electrochemical Impedance Spectroscopy (EIS) is extensively used to characterize Solid Oxide Cells (SOCs) to extract information on the elementary loss mechanisms. However, these individual mechanisms usually overlap in the frequency domain, requiring dedi ...
ELSEVIER2019Modeling and experimentation of conductive and radiative transfer through heterogeneous insulators in high-flux environments
Heterogeneous materials are used in a wide range of applications involving high heat flux environments such as concentrated solar reactors, high-temperature furnaces, or thermal protection systems of space vehicles. The thermal response of heterogeneous ma ...
EPFL2019Analysis of High Temperature Degradation of Alloys in Solid Oxide Fuel Cell
Solid oxide fuel cells (SOFCs) are approaching commercialization to improve power production efficiency. Currently, cost and lifetime reliability limit their spread in the market. The SOFC is ceramic-based, but refractory metal alloys are in fact the major ...
