abstract = {Climate change, energy security and air pollution are all
motivators for the further development of fuel cells. A
volume of fluid approach was used to investigate the impact
of dynamic contact angle boundary conditions (Kistler
model), mainly at the gas diffusion layer surface but also
at the channel wall, of a polymer electrolyte fuel cell gas
channel. From this study, it is clear that a dynamic contact
angle boundary condition, with advancing and receding
contact angles, influences the droplet detachment
characteristics, for example, the detachment time and
droplet size. Implementing dynamic contact angle boundary
conditions for a thin channel causes the droplet, after
being reattached to the wall on the side opposite the GDL,
to flow very slowly when attached to the wall, until it is
merged with a second droplet and they exit the channel (but
remain attached to the wall) fairly quickly. Similar
phenomena are not observed while using a static contact
angle.},
