abstract = {In order for electrolysis cells to operate optimally, mass
transport must be improved. The key initial component for
optimal operation is the current collector, which is also
essential for mass transport. Water as an educt of the
reaction must be evenly distributed by the current collector
to the membrane electrode assembly. As products of the
reaction, hydrogen and oxygen must also be directed quickly
and efficiently through the current collector into the
channel and removed from the cell. The second key component
is the stoichiometry, which includes the current density and
water volume flow rate and represents the ratio between the
water supplied and water consumed. This study presents the
correlation of the stoichiometry, two-phase flow in the
channel and gas fraction in the porous transport layer for
the first time. The gas-water ratio in the channel and
porous transport layer during cell operation with various
stoichiometries was investigated by means of a model in the
form of an ex situ cell without electrochemical processes.
Bubble formation in the channel was observed using a
transparent cell. The gas-water exchange in the porous
transport layer was then investigated using neutron
radiography.},
