In order to investigate the humidity recovery from the exhaust gas of the fuel cell vehicle by using micro porous plate, experimental apparatus to examine the performance in the heat and mass transfer between water and air through the micro porous plate was established. The effects of experimental method and property of materials, such as impregnation, hydrophilicity treatment and pore diameter etc., on mass transport were measured. It was shown that the effects of impregnation and pore diameter on mass transport vary with the thickness and pore diameter of porous plate. Further, the variation of mass transport caused by hydrophilic treatment for porous plate is not observed in the conditions of the experiment.
