Proton Exchange Membrane Nanocomposites
2010Organic-inorganic nanocomposite proton conducting membranes have been an important thrust in the search for novel materials that outperform the state-of-the-art all-polymer membranes in fuel cells. Nanocomposite proton exchange membranes may provide routes to increased conductivity at low relative humidity, decreased methanol permeability without a ...

One-Pot Synthesis of Proton Exchange Membranes from Anion Exchange Membrane Precursors
ACS Macro Letters, 2020Proton exchange membranes (PEMs) play a critical role in many electrochemical devices that could solve the shortcomings of current energy storage and conversion systems. Hydrocarbon-based PEMs are an attractive alternative for replacing the state-of-the-art perfluorosulfonic acid PEMs; however, synthetic routes are generally limited to sulfonation of ...

Stereochemistry-Dependent Proton Conduction in Proton Exchange Membrane Fuel Cells
Langmuir, 2015Graphene oxide (GO) is impermeable to H2 and O2 fuels while permitting H(+) shuttling, making it a potential candidate for proton exchange membrane fuel cells (PEMFC), albeit with a large anisotropy in their proton transport having a dominant in plane (σIP) contribution over the through plane (σTP).

FUEL CELLS – PROTON-EXCHANGE MEMBRANE FUEL CELLS | Membranes: Polybenzimidazole
2009The current research on polymer electrolytes for fuel cells is focused on the optimization of a membrane working at 120 °C and low humidity levels (<30%), which are the real operative conditions in the case of automotive applications. Among a wide variety of tested polymer systems, polybenzimidazole (PBI)-based membranes, doped with phosphoric acid,

Advances in ionogels for proton-exchange membranes
Science of The Total EnvironmentTo ensure the long-term performance of proton-exchange membrane fuel cells (PEMFCs), proton-exchange membranes (PEMs) have stringent requirements at high temperatures and humidities, as they may lose proton carriers. This issue poses a serious challenge to maintaining their proton conductivity and mechanical performance throughout their service life ...
