Area of Science:

  • Materials Science
  • Electrochemistry
  • Polymer Science

Background:

  • Proton exchange membranes (PEMs) are crucial for fuel cells.
  • Anhydrous proton conduction remains a challenge for PEMs, especially at high temperatures.
  • Functionalized graphene oxide (FGO) and sulfonated poly(ether ether ketone) (SPEEK) offer potential for improved membrane properties.

Purpose of the Study:

  • To fabricate and characterize novel nanocomposite membranes for anhydrous proton conduction.
  • To investigate the role of functionalized graphene oxide (FGO) in enhancing ionic liquid (IL) uptake and proton conductivity.
  • To explore the relationship between interfacial microstructure, IL storage, and proton transport in SPEEK-FGO-IL systems.

Main Methods:

  • Fabrication of nanocomposite membranes by incorporating imidazole-type ionic liquid (IL) into functionalized graphene oxide (FGO) and sulfonated poly(ether ether ketone) (SPEEK) matrices.
  • Characterization of membrane microstructure, free volume, and interfacial interactions.
  • Measurement of IL uptake, retention, and anhydrous proton conductivity at elevated temperatures.

Main Results:

  • The p-styrenesulfonic acid functionalized GO (SGO)-based nanocomposite membrane exhibited significantly higher IL uptake (73.7%) compared to other FGOs.
  • The SGO-SPEEK-IL nanocomposite membrane achieved a maximum anhydrous proton conductivity of 21.9 mS cm(-1) at 150 °C, over 30 times that of the SPEEK control.
  • Enhanced electrostatic interactions between SGO and ILs improved IL retention within the membrane.

Conclusions:

  • Functionalized graphene oxide, particularly SGO, effectively enhances IL loading and retention in SPEEK-based membranes.
  • The developed nanocomposite membranes demonstrate superior anhydrous proton conductivity, driven by ILs acting as proton hopping sites within tailored interfacial channels.
  • These findings highlight the potential of SGO-SPEEK-IL nanocomposite membranes for high-temperature, water-free fuel cell applications.
