This change results in advance efficiency; furthermore, which efficiency is better than ready-made MEA. The open circuit voltage(OCV) is increased 18% and the maximum power density is also raised 5.5%;moreover, the weight of catalyst is decreased 10% and the thickness of MEA is decreased about 11%.The above-mentioned things are what MEA can reduce cost and thickness. The degree of hydrophobia on Gas Diffusion Layer(GDL) influence efficiency of MEA, in this research we compare many samples. Finally we need not to increase the hydrophobia in GDL, which is enough to provide the path of methanol and gas. This research have detailed treat in correlation between hydrophobia and efficiency.
