CO₂ bubble and water droplet generated respectively in anode and cathode catalytic layers of DMFC have adverse effects on the transport of methanol and air to the catalytic layers, if they are not properly exhausted from the pores of MDL and quickly detached from the surface of MDL. In this study, we experimentally tested the wettability effect of MDL on the performance of DMFC and further studied its enhancement via micro-perforation of MDLs. It was found that the attached shapes and issuing characteristics of the byproducts are significantly affected by the MDL's wettability and more power was obtained for the combination of hydrophilic anode and hydrophobic cathode MDLs. Moreover, we obseved the power enhancement via the micro-perforation by 21.3%.
