We investigate the temperature-dependent gas saturation in the porous transport layer (PTL), and the subsequent impact of this gas saturation on the mass transport overpotential of a polymer electrolyte membrane (PEM) electrolyzer. Via in operando neutron imaging of a PEM electrolyzer, we observe th...
