New Anhydrous Proton Exchange Membrane for Intermediate Temperature Proton Exchange Membrane Fuel Cells

ChemPhysChem, 2011
AbstractHerein, we study the preparation and characterization of a new kind of proton exchange membrane. In the proton‐conducting membrane of poly(vinylidene fluoride) (PVDF)/poly(ethylene oxide) (PEO)/dodecyl benzenesulfonic acid (DBS‐H), we use PEO as “proton solvent” due to its flexible molecular chain.

Inorganic Proton Exchange Membranes

ASME 2006 Fourth International Conference on Fuel Cell Science, Engineering and Technology, Parts A and B, 2006
Direct Methanol Fuel Cells (DMFCs) offer advantages from quick refills to the elimination of recharge times. They show the most potential in efficient chemical to electrical energy conversion, but currently one major source of inefficiency within the DMFC system is the electrolyte allowing fuel to cross over from the anode to cathode.

Proton Exchange Membrane Electrochemical Capacitors

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 2005
Disclosed is a high-energy-density all-solid ionomer electrochemical capacitor, completely free of liquid electrolyte. The capacitor includes 1) a three-dimensional metal oxide-particulate-ionomer composite electrode structure, whereby the ionomer coats the individual particles and provides a mechanism for continuous proton transport throughout the ...

Protein-Functionalized Proton Exchange Membranes

Design, Synthesis, and Applications, 2004
Protein-functionalized biomimetic membranes, based upon a triblock copolymer simulating a natural lipid bilayer in a single chain, serves as a core technology for applications in bioenergetics. Monolayers of block copolymer, which simulates the hydrophilic-hydrophobic-hydrophilic chain of a natural cell membrane, can be formed by Langmuir-Blodgett (LB)

Biomimetic N-Doped Graphene Membrane for Proton Exchange Membranes

Nano Letters, 2021
Proton exchange membranes (PEMs) with both high selectivity and high permeance are of great demand in hydrogen-based applications, especially in fuel cells. Although graphene membranes have shown high selectivity of protons over other ions and molecules, the relatively low permeance of protons through perfect pristine graphene restricts its practical ...

Proton Exchange Membrane Water Electrolysis

2020
Proton exchange membrane water electrolysis (PEMWE) technology is a high efficiency and clean route to extract H2 from pure water. As the converse process to the-state-of-the-art H2 fuel cell, PEMWE possess several merits including high energy conversion, zero emission, and the production of high purity H2.
