英文摘要	in this study, a fractal model is developed to predict the permeability and liquid water relative permeability of the gdl (tgp-h-120 carbon paper) in proton exchange membrane fuel cells (pemfcs), based on the micrographs (by sem, i.e. scanning electron microscope) of the tgp-h-120. pore size distribution (psd), maximum pore size, porosity, diameter of the carbon fiber, pore tortuosity, area dimension, hydrophilicity or hydrophobicity, the thickness of gdl and saturation are involved in this model. the model was validated by comparison between the predicted results and experimental data. the results indicate that the water relative permeability in the hydrophobicity case is much higher than in the hydrophilicity case. so, a hydrophobic carbon paper is preferred for efficient removal of liquid water from the cathode of pemfcs.
