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.

Proton exchange membrane fuel cells

Vacuum, 2006
The desire to have compact, high power sources with low environmental impact has focused attention on proton exchange membrane fuel cells (PEMFC). The paper gives a brief overview of processes and technical challenges related to PEMFCs. The main goal is also to give a short overview of the underlying science and to show a feasible approach to ...
