However, the H3PO4 molecules behave like islands cooperating with imidazole –NH and –N=C groups to provide binding sites for H+ ions to hop in the PBI/H3PO4 complex membranes. No water molecules are required to conduct the protons, and thus the PBI/H3PO4 membranes are suitable for low-humidity HT-PEMFCs. 25)  make the PBI membranes brittle, which restricts the H3PO4 doping level and limits the applications of PBI membranes to HT-PEMFCs. 24 Proton hopping mechanism in the H3PO4 doped PBI membranes, in which H3PO4 molecules act as proton carrier.
