Special Issue Information

Dear Colleagues,

The world is witnessing and experiencing major issues arising from climate change. Electrochemical converters play crucial roles in mitigating these issues. Among them, solid oxide cells (SOCs) are able to operate in fuel cells (SOFCs), electrolysis cells (SOECs) or even reversible solid oxide cells (RSOC) with different gas components, which represent a very promising technology for carbon-neutral attainment and decarbonization. SOCs exhibit relatively high efficiency but face challenges from electrode/cell material science, stack assembling, thermal management, system integrity and control, etc. To overcome these challenges, various computational and modeling techniques have been proposed and developed which allow for the systematic simulation, design and optimization of SOCs at different levels, aiming to provide valuable insights into the phenomena occurring within the cells, stacks and systems that reduce the development cycles.

This Special Issue aims to present and disseminate the most recent advances related to modern modeling and simulation technologies, as well as applications ranging from material design to system control in the field of SOCs, including SOFCs, SOECs and RSOCs.

Topics of interest for publication include but are not limited to the following:

  • All aspects of modeling and simulation in the field of SOCs;
  • Physical models, data-driven models and hybrid methods;
  • Static and dynamic operating performance evaluated by various models and simulations;
  • Control strategy-oriented modeling and simulation;
  • Technoeconomic analysis;
  • Advanced modeling and simulation approaches;
  • Model fidelity.

The reversible solid oxide cell model is established by COMSOL Multiphysics® (version 5.4) software under multi-physics coupling. According to the governing equation, the simulations were conducted based on the same parameters for many control groups numerically. At the same time, a comparison of these results was involved. For the air electrode in SOFC mode, the performance of the fuel cell will increase with the increase in the porosity. For the fuel electrode in SOFC mode, the increase is much greater than the impact of the porosity. The design parameters compared in this simulation are used to simulate and analyze and predict fuel cell performance under different conditions. The design parameters related to the electrode microstructure are defined in this model as: porosity (electrode porosity), pore size (electrode internal average pore size), and permeability (electrode internal permeability).

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. Full article
