Enhancement of sulfonated poly(ether ether ketone)-based proton exchange membranes doped with different ionic liquids cations

Universidade Federal de São Carlos (UFSCar); Universidade Estadual Paulista (Unesp); Universidade Federal do Rio Grande do Sul (2020-01-01)

Herein, to balance the overall performance of SPEEK membrane, the imidazolium hydrogen sulfate (Im.HSO4), 1-methylimidazolium hydrogen sulfate (MI.HSO4), and 1-butyl-3-methylimidazolium hydrogen sulfate (BMI.HSO4) ionic ...

The influence of ionic liquids cation on the properties of sulfonated poly (ether ether ketone)/polybenzimidazole blends applied in PEMFC

Universidade Federal do Rio Grande do Sul; Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP); Universidade Federal de São Carlos (UFSCar) (2019-09-28)

Blends modified with ionic liquid (IL) can have their conductivity improved at elevated temperatures and low relative humidity (RH) making them suitable for proton exchange membrane fuel cells (PEMFCs) applications. This ...
