A Control-Oriented Modelica 1-D Model of a Planar Solid-Oxide Fuel Cell for Oxy-Combustion Cycles

The authors propose an object-oriented Modelica 1-D SOFC model following the indications of a previous work. The model is intended to be used in the study of the SOS-CO
2
cycle for control studies purposes. The SOFC working conditions are challenging and require adapting the model to handle properly reformate mixtures at the anode and carbon dioxide-rich mixtures at the cathode while keeping its formulation as simple as possible. This paper reviews the previous contribution, adapts the model for the new working conditions, provides insights related to the Modelica implementation, reproduces the tests presented in literature and extends the validation through a comparison with experimental data. Finally the model is tested under SOS-CO
2
cycle operative conditions.
