Beschreibung

Reversible solid oxide cells (rSOCs) have the capacity to produce hydrogen using electricity generated from intermittent renewable sources and to reverse the process within the same system to generate electricity. This dual functionality positions the technology as a key component of green energy systems, offering the highest efficiency, broad feedstock compatibility, and operational flexibility compared to PEM and alkaline technologies. Certain operational parameters, particularly pressure, can significantly enhance physical and economic efficiency.

To achieve these efficiency gains, the cells must operate under dynamic conditions—such as fluctuating pressures and temperatures—characteristic of hydrogen production and grid-balancing applications. However, these conditions induce significant mechanical stresses on rSOCs, potentially compromising their durability. Advanced theoretical modeling of these stresses is essential to optimize cell architecture, enhance operational resilience, identify suitable operational parameters for experimental investigations, and ensure the long-term reliability of rSOCs in enabling a sustainable, hydrogen-powered future.

To achieve these goals, a finite element method (FEM) model must be developed to analyze the mechanical loads on materials under various support structures and cell geometries. Operational parameters of the reaction and mechanical properties from literature will serve as inputs to assess the stability and performance of the cells.
