Mathematical modeling and simulation of hydrogen-fueled solid oxide fuel cell system for micro-grid applications - Effect of failure and degradation on transient performance
Colombo, Konrad Werner Eichhorn; Kharton, Vladislav V.,; Berto, Filippo; Paltrinieri, Nicola (Peer reviewed; Journal article, 2020)We use a detailed solid oxide fuel cell (SOFC) model for micro-grid applications to analyze the effect of failure and degradation on system performance. Design and operational constraints on a componentand system level are ... -
Mathematical Multi-physics Modeling and Simulation of a Solid Oxide Fuel Cell Unit for Thermo-Mechanical Stress Analyses
Colombo, Konrad Werner Eichhorn; Kharton, Vladislav V.,; Berto, Filippo (Peer reviewed; Journal article, 2020)We use a mathematical model of a solid oxide fuel cell (SOFC) unit for stress analyses. The model comprises a thermo-electrochemical-chemical performance model that calculates the temperature field in the solid part which ... -
Transient simulation of failures during start-up and power cut of a solid oxide fuel cell system using multiphysics modeling
Colombo, Konrad Werner Eichhorn; Kharton, Vladislav; Berto, Filippo; Paltrinieri, Nicola (Journal article; Peer reviewed, 2021)We investigate failure incidents of a solid oxide fuel cell (SOFC) system during start-up from ambient conditions as well as during operation around the design point, using numerical simulation with a view to performance ... -
Transient system-level performance and thermo-mechanical stress analysis of a solid oxide fuel cell-based power generation plant with a multi-physics approach
Colombo, Konrad Werner Eichhorn; Kharton, Vladislav V.,; Berto, Filippo; Paltrinieri, Nicola (Journal article; Peer reviewed, 2020)A solid oxide fuel cell-based (SOFC) power generation plant is analyzed with a view to performance as well as thermo-mechanical stresses. Emphasis is given to design and operation constraints of individual components as ...
