Inspired The growing demand for energy, associated with the finite and polluting nature of most current energy sources, motivate the search for new, more efficient, renewable means, that also pose less environmental impacts. In this context, the great potential presented by fuel cells as part of this effort is evident. This project aims to develop a simulator, programmed in MATLAB, which allows the analysis of exergoeconomic indicators related to the operation of a Proton Exchange Membrane Fuel Cell (PEMFC), fueled with pure hydrogen. The validation of the implemented model was done through the comparative analysis between the results generated by the simulation and the theoretical and experimental results obtained through a bibliographic review. The effects of temperature and pressure variations associated with current density variations were analyzed. It was possible to conclude that higher temperature and pressure have positive impacts on exergetic and energy efficiencies, on the power output, and on the exergetic cost of the power output. It was also observed that for a specific range of current density, between 0 and about 1.2 A/cm2, higher densities translate into higher power output. However, higher current densities are always associated with lower efficiencies and higher exergetic costs. By performing a sensitivity analysis, the effects of temperature, pressure, current density, stoichiometries, hydrogen cost, annual interest rate, and cell acquisition cost were investigated. The positive effect of reducing the stoichiometry of hydrogen on the exergetic cost of power and energy efficiency can be observed, an improvement of up to 20% and 25% when reducing the stoichiometry by 20%, respectively. Still related to hydrogen, the decrease in its exergetic cost causes a significant decrease in the exergetic cost of the generated power, and its increase also causes an increase in the power cost, in both cases by up to 20%, for the analyzed interval. Finally, the sensitivity analysis showed that despite being parameters considered in the calculation of the exergetic cost of the cell power output, the annual interest rate and the cell acquisition cost have a marginal influence on this result.
