Simulation of PEMFC performance

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 polarization curve and consider FC as a black box. The aim of this study is to
present a simple but enhanced and accurate expression of PEMFC output voltage. The
model includes operative conditions, current density and geometric parameter of the FC.
