Beschreibung

Background

Reversible solid oxide cells (R-SOCs) can operate in both fuel cell mode and electrolysis mode. Due to their high efficiency, high-temperature operation, and versatility, R-SOCs exhibit potential advantages in various application scenarios[1]. During the mode-switching process, the uneven temperature distribution of the stack will lead to uneven temperature changes between different cells, generating variable thermal stresses[2]. In practical and dynamic operation, the thermal stress at the interface of different layers can cause cracks or even thermal mechanical failure[3], which are key problems and research targets.

 

Objectives

The aim is to investigate the effect of operating mode switching on interfacial delamination and to explore corresponding optimization strategies. Key tasks include multiphysics simulation, thermomechanical analysis, and performance optimization.
