Abstract: Solid oxide fuel cells are designed to operate in a wide temperature range (600–1000 °C). Operation at high temperature enhances the cell performance, but retains intrinsic problems such as poor long-term stability and high manufacturing cost. Recent studies have directed to the operation in intermediate temperature with incorporating the anode-supported solid oxide fuel cells. Here, we investigate the performance of anode-supported solid oxide fuel cells using a computational fluid dynamics based open-source software. We develop a complete overpotential model based on open-source fuel cell code. This model predicts the cell performance and provides insight into the transport phenomena and electrochemical characteristics. To validate our numerical model, we compare the simulated results with experimental data at intermediate temperatures. The cell performance is decomposed into several component overpotentials to understand the contribution of each one on the overall potential loss. The reduction of electrolyte overpotential is explored to attain high performance at intermediate temperature by investigating the influence of the electrolyte thickness and alternative electrolyte material on the cell performance.
