Experimental validation and modeling of SOFC systems fueled by dark fermentation biogas and alternative fuel mixtures

Solid Oxide Fuel Cells (SOFCs) offer high-efficiency power generation with low emissions, especially when fueled by renewable energy carriers. This thesis investigates the experimental validation and modeling of SOFC systems operating with dark fermentation biogas and alternative hydrogen fuel mixtures. Experimental SOFC current-voltage-power curves are analyzed and modeled to assess system performance. The models are developed in AVL Cruise™ M and validated against experimental results, showing good agreement with measured data. The validated models are then used to evaluate the impact of different fuel blends, confirming the potential of dark fermentation biogas and hydrogen blends as viable renewable fuels for high-temperature fuel cell applications.
