Mesoscale Simulation of Proton Transport in Proton Exchange Membranes
The Journal of Physical Chemistry C, 2012Previous efforts to model proton transport through fuel cell membranes have largely focused on disparate length scales: molecular dynamics at the atomistic level and fuel cell stack engineering app...

Abstract Mechanical degradation, caused by local stress concentration and variation, significantly affects the lifetime of proton exchange membrane fuel cells. This study constitutes the first numerical investigation of stress evolution in the membrane between the frame of the membrane exchange assembly (MEA) and gas diffusion layer (GDL) throughout ...

Proton Exchange Membrane Electrochemical Capacitors
Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 2005Disclosed 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 ...

Proton Exchange Membrane Water Electrolysis
2020Proton 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 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 ...
