abstract = {A computational fluid dynamics model of a channel (one
liquid inlet, one liquid inlet and one two-phase outlet),
applicable for PEFC gas channel water transport, is
developed. A volume of fluid approach is used to study the
two-phase flow behavior (interface-resolved) inside the gas
channel, including the surface of GDL (gas diffusion layer),
which is verified by experimental results from synchrotron
based X-ray radiography and tomography imaging. A reasonably
good agreement is found between the model and the
measurements in terms of droplet dynamics, shape, and size.
The channel height strongly influences the droplet transport
behavior, with the droplet being attached to the GDL
surface, as well as to the wall on the opposite side to the
GDL at the same time for the shallowest channel (150 μm).
The GDL contact angle influences the droplet size, with an
increased GDL contact angle creating smaller droplets.},
