N2 - Effects of hydrophobic treatment and MPL (Micro Porous Layer) in PEFC were investigated by experiments at starting test procedure mode. Hydrophobic treatment decreases accumulated water in DGL (Gas Diffusion Layer), and increases it on cathode electrode, which disturbs gas diffusion and makes PEFC output voltage lower. Coating of MPL on GDL protects cathode electrode wetting and improves PEFC performance. Improvement of gas permeability of GDL matrix makes not only gas diffusion to cathode electrode smooth but also exhausting of product water vapor from electrode to gas channel active, and these two merits improve PEFC performance under flooding obstruction at starting procedure mode.
