Simulation of PEMFC performance
Journal of Renewable Energies, 2023 Throughout literature, there are two approaches to estimate fuel cells (FC) performance, by the evaluation of polarization curve. One includes, physical modelling of heat and mass transfer with electrochemical phenomena; the second is based on semiempirical equation used in order to analysis the effect of different physical perturbation on the ...
