Optimized design of planar solid oxide fuel cell interconnectors

Solid oxide fuel cells (SOFCs) are vital for alternative energy, powering motors effi-ciently. They offer fuel versatility and waste heat recovery, making them ideal for various applications. Optimizing interconnector structures is crucial for SOFC advancement. This paper introduces a novel 2D simulation model for interconnector SOFCs, aiming to enhance their performance. We initially construct a single half-cell model for a conventional interconnector SOFC, ensuring model accuracy. Subsequently, we propose an innovative interconnector SOFC model, which outperforms the conventional counterpart in various aspects. The components of an SOFC, including cathode, electrolyte, anode, and metal-interconnector support [6,7], impacts performance and efficiency. Each composition has its advantages depending on specific requirements. Interconnectors play a vital role in SOFCs by distributing airflow, delivering fuel and oxygen, and outputting reaction products [8–10]. The choice of interconnector material is crucial to maintaining stability and performance [11–21].
