This study presents an improved Tank in Series Reactor (TSR) Proton Exchange Membrane (PEM) fuel cell model with mass and energy balance equations accounting for evaporation and condensation in cathode channels. The TSR model includes the modified charge balance equation suitable for potentiostatic fuel cell operation mode. Polarization curves calculated with the improved model agree with experimental data from the literature. The developed TSR model is able to predict the limiting two-dimensional profiles in PEMFC. Simulation results illustrate the influence of co-current and counter current mode on PEM fuel cell performance.
► The improved TSR model describes two-dimensional concentration, temperature and current density profiles in PEM fuel cells.
► The improved model includes the charge balance equations defined as interface boundary conditions.
► Case studies show comparison of PEMFC performance with co-current and counter current flow of fuel and oxidant.
► TSR model is applicable for galvanostatic and potentiostatic operation modes of PEM fuel cells.
