** To run the model
- download Dec18FulldayData.mat, Dec17_validation_alpha_11_5_all.mat, Tuning_data_Dec18.mat
- open GDLmodel.mdl
- run Run_GDL_model.m
- run voltage_parameterization_linear_jason_time.m (tune the voltage and plot variables)

** Description of files and folders
fcsparams.m - fuel cell parameters and data constants
GDLModel.mdl - Simulink model
mscaledata - convert raw data to SI units
mscaledata_a - convert data back to non-SI units for plotting as in publication
satpressure.m - Calculate saturation pressure as a function of temperature
voltage_parameterization_linear_jason_time.m - tunes the model and creates figures from publication


** The model is created by
