Proc. ASME. FUELCELL2010, ASME 2010 8th International Fuel Cell Science, Engineering and Technology Conference: Volume 1, 91-98, June 14–16, 2010
Paper No: FuelCell2010-33186
..., the reactant microjets impinge on the back side of the flow field plate before wrapping around and traversing the flow field channels where they are involved in electrochemical activity. However, it was observed that the fuel cell was subject to significant flooding, which limited its continuous operation...

Proc. ASME. FUELCELL2008, ASME 2008 6th International Conference on Fuel Cell Science, Engineering and Technology, 821-828, June 16–18, 2008
Paper No: FuelCell2008-65209
.... It was also shown that the establishment of gas paths in the deep layer of GDL by the channels filled with condensed water is effective for stable operation at low flow rates of air in the straight channels. PEM fuel cell Gas diffusion layer Cross-over Flow Separator type Flooding over flow under...

Proc. ASME. FUELCELL2005, 3rd International Conference on Fuel Cell Science, Engineering and Technology, 25-29, May 23–25, 2005
Paper No: FUELCELL2005-74037
... An increase in pressure drop on the cathode side of PEM fuel cell is a reliable indicator of PEM fuel cell flooding. Flooding, i.e., liquid water accumulation inside the cell causes a rather erratic cell potential behavior — steady voltage drops followed by sudden voltage increases. The pressure...

Proc. ASME. FUELCELL2006, ASME 2006 Fourth International Conference on Fuel Cell Science, Engineering and Technology, Parts A and B, 97-104, June 19–21, 2006
Paper No: FUELCELL2006-97041
... height, chord length, and level of surface hydrophobicity of the DM directly affect the droplet instability. At high flow rates, the surface hydrophobicity of the DM enhances the efficacy of droplet removal, and helps to avoid local channel flooding, however at low flow rates, regardless of the amount...
