Biogas can be used as a fuel in Solid Oxide Fuel Cells (SOFCs) for efficient power generation from a renewable source. However biogas is, in general, a complex fuel and much work is still needed to identify and remedy possible issues that might arise when used in SOFCs. In this study a SOFC operating on simulated biogas is modeled using an in-house computer code, namely DREAM-SOFC. The model solves for mass transfer, energy balance, electrochemistry and bulk chemical reactions inside the SOFC. Internal reforming of biogas is accounted for through both wet and dry reforming of methane. The model predictions of the cell performance curve are compared with the data from experiments also performed at West Virginia University for validation. The model is then used to predict the concentration distribution of species as well as the temperature distribution in the cell at different operating conditions.
