The effect of PEMFC trapezoidal channel wall contact angle on water removal characteristics is
investigated with the volume of fluid (VOF) method. Two different contact angles 60 and 90 degrees
are selected. In the case of the side and top wall contact angle of 60 degrees, stable semi-spherical
droplets move along the top wall slowly. In contrast, complex shaped droplets move along the lower
edge in the case of 90 degrees. Moreover, it is shown that very complex interaction patterns between
different droplets which introduced into the channel at different times.
