The influence of channel wettability and geometry on water plug formation and drop location in a proton exchange membrane fuel cell flow field

► We have successfully modeled the minimum volume required to plug a fuel cell channel. ► The effect of degradation of fuel cell components on channel flooding is assessed. ► The utility of Surface Evolver for fuel cell designed has been shown. ► Combinations of bipolar plate and GDL wettabilities can passively move water.
