Water content and water-content difference along the through-plane direction of a fuel cell with a Nafion 1140 membrane during OCV and operating at a current density of 0.135 A/cm2 and 0.1V with H2 and O2 gases humidified at 100% RH. The vertical lines denote the boundary between the MEA and the GDLs; the cathode channel and GDL regions range between 500 μm to 1250 μm, the anode channel and GDL regions range between 2250 μm and 3000 μm.
