Although the mechanical performance of SOFC is equally significant, it has received relatively less research attention and remains inadequately addressed. Currently, mathematical models and finite element simulations are utilized to investigate the mechanical and electrochemical performance of SOFC stacks. Given that the electrochemical performance of electrode materials is governed not only by their inherent catalytic activity but also by geometric factors, particularly the active surface area, it is essential to develop electrochemical cells composed of nanoscale particles and to preserve their morphology during high-temperature

Onda et al. [14] developed a two-dimensional model for a PEM water electrolyzer. They used empirical equations based on the temperature and cell current density.
