      abstract     = {Energy security, climate change and air pollution are all
                      motivations for further development of fuel cells. Still,
                      technical problems relating to water management, continue to
                      hinder the marketability of polymer electrolyte fuel cells
                      (PEFCs). The impact of dynamic contact angle (CA) boundary
                      conditions, according to the Kistler model, is evaluated in
                      this paper with the VOF approach, focusing on droplet
                      reattachment at the gas channel wall. From this, it is clear
                      that dynamic CA boundary conditions, compared to static CA
                      boundary conditions, significantly influence the droplet
                      reattachment characteristics, for example for the standard
                      case with a gas velocity of 10 m/s, the first droplet
                      awaits attachment to the channel wall on the side opposite
                      the gas diffusion layer surface for a second droplet before
                      merging and then moving out of the channel together,
                      attached to the channel wall. The impact from dynamic CAs
                      becomes even bigger for lower velocities (5 m/s in this
                      case), where the droplet residence time increases
                      significantly. It is clear that the channel dimensions, gas
                      inlet velocity and value of CAs, as well as if a static or
                      dynamic CA model is used, all have a significant impact on
                      the droplet characteristics in PEFC GCs.},
