Abstract:

In the compelling need for decarbonization of the transport and energy sectors, hydrogen could play an important role, both as an energy carrier and as a long-term storage medium for intermittent renewable energies such as solar and wind. The usage of hydrogen as a fuel for the transport sector seems to be the optimal solution wherever weight and range are the main constraints, like for heavy-duty transport, trains, cargo ships, and airplanes. Hydrogen chemical energy can be converted into mechanical or electrical energy mainly in two ways, by means of a combustion process in Internal Combustion Engines, or by means of electrochemical conversion in Fuel Cells. The aim of this dissertation is therefore to create a model of a Proton Exchange Membrane Fuel Cell (PEM-FC) system in commercially available software, GT-Suite. Before studying the system layout, a deep analysis of the stack model is done. The model under consideration allows numerous dynamic loss calculations. Some of the most important are activation losses with the Butler-Volmer equation and internal-ohmic resistance losses with Springer- Zawodzinski; this allows a dynamic calculation of the cell voltage based on the reactant’s conditions. A process to calibrate the losses is then proposed in order to fit the experimental data of the polarization curve at the operational conditions of the Fuel Cell stack. Established a robust calibration procedure, the focus of the dissertation shifts to the balance of plant, with the aim to find the most efficient solutions. The GT-Suite library allows the addition of the auxiliaries’ components, compressor, turbine, etc. Different layouts configuration and operating conditions are examined, under stationary conditions.
