“…(5) The anode, electrolyte layer, and cathode materials are isotropic and linear elastic materials. (6) The thermophysical characteristics of all materials composing the SOFC stack remain constant, irrespective of the local temperature. (7) The anode, cathode, and electrolyte layer interfaces, along with the connecting body and sealing material, form a continuous structure that permits collective deformation without fracturing.…”

“…A few of the published work have been conducted for various aspects of SOFCs in general, from micro-to macroscopic scales using various numerical analysis methods, as outlined in [6]. Some of these studies focus on SOFC stack operating processes and overall performance including the thermal stress distribution but mainly take the loopedmaterial components or even assume the positive/electrolyte/negative (PEN) as a grouped cell component [7].…”

Mechanical failures in the operating stacks of solid oxide fuel cells (SOFCs) are frequently related to thermal stresses generated by a temperature gradient and its variation. In this study, a computational fluid dynamics (CFD) model is developed and further applied in full-size SOFC stacks, which are fully coupled and implemented for analysis of heat flow electrochemical phenomena, aiming to predict thermal stress distribution. The primary object of the present investigation is to explore features and characteristics of the thermal stress influenced by electrochemical reactions and various transport processes within the stacks. It is revealed that the volume ratio of the higher thermal stress region differs nearly 30% for different stack flow configurations; the highest probability of potential failure appears in the cell cathodes; the more cells applied in the stack, the greater the difference in the predicted temperature/thermal stress between the cells; the counter-flow stack performs the best in terms of output power, but the predicted thermal stress is also higher; the cross-flow stack exhibits the lowest thermal stress and a lower output power; and although the temperature and thermal stress distributions are similar, the differences between the unit cells are bigger in the longer stacks than those predicted for shorter stacks. The findings from this study may provide a useful guide for assessing the thermal behavior and impact on SOFC performance.

“…The system failure probability function is built based on the experimental data and physics-based deterioration model. Reliability analysis of a MFC from a system engineering perspective is presented by Colombo and Kharton [29]. They systematically demonstrate the methodology of combining physical modeling and experimental data to construct system failure probability which is inspiring for fuel cell-based system reliability studies.…”

Model‐based systems engineering (MBSE) is part of a long‐term trend toward model‐centric approaches adopted by many engineering disciplines. We establish the need of an MBSE approach by reviewing the importance, complexity, and vulnerability of the U.S. chemical supply chains. We discuss the origins, work processes, modeling approaches, and supporting tools of the systems engineering discipline (SE) and discuss limitations of the Process Systems Engineering (PSE) framework. We make the case for MBSE as a more generalizable approach. We introduce systems modeling strategies for MBSE, and a novel MBSE method that supports the automation tailored and extended to support the analysis of chemical supply chains. We demonstrate a specific use case of this method by creating a systems model for the manufacturing of an active pharmaceutical ingredient, Atropine. We conclude with a prospectus on developmental opportunities for extracting greater benefit from MBSE in the design and management of chemical supply chains.
