Temporal variation and spatial distribution of interfacial mass-transfer rate in the cathode side gas diffusion layer (GDL) of a proton exchange membrane fuel cell during start-up were numerically investigated. For this purpose, a 3D transient two-phase nonisothermal model was used. A nonequilibrium evaporation-condensation interfacial mass-transfer rate is incorporated in the model, which enables us to take supersaturation and subsaturation into consideration. This helps us to investigate the most significant contribution of the phase-change rate to the transient response and thermal behavior of the cell.
