Semi-interpenetrating polybenzimidazole membrane containing polymeric ionic liquid with high power density and enhanced proton conductivity for fuel cells

[Display omitted] •A series of semi-interpenetrating membranes was successfully prepared.•The proton conductivity of AmPBI-PIL-30 at 180 °C is 1.9 times higher than AmPBI.•After PA retention test for 240 h, AmPBI-PIL-30 shows pretty proton conductivity.•Great power density (635.4 W cm−2) under 160 °...
