groups which can easily form hydrogen bonds and encourage proton transfer in low RH is synthesized and doped into the PBI-based membranes. The epoxy groups of tetrafunctional N, N, N’, N’-tetraglycidy-4,4'-diaminodiphenylmethane (TGDDM) react with the NH groups in polybenzimidazole (PBI) and form a cross-linking network structure to improve the mechanical properties, oxidative stability and dimensional stability of the composite membranes. At 180 °C, the proton conductivity of the mPBI-TGDDM (10%)/ZrEDTMPS (30%) is 0.122, 0.050, and 0.029 S cm

at 100%, 50%, and 0 RH, respectively. Meanwhile, the mPBI-TGDDM/ZrEDTMPS membranes exhibit high oxidative stability (the mass loss of membranes is 2.1%). Compared with Nafion 117 (5.5 × 10
