... as the preferred region where water tends to cumulate at the anode of PEMFCs. Second, the bigger the relative GDL height, the smaller the number of sites in liquid phase (i.e., the percent of liquid water) in the whole domain and particularly in the GC–GDL interface. This relation indicates that water...
