Polymer electrolyte fuel cells (PEFCs) are a promising replacement for the fossil fuel–
dependent automotive and energy sectors. They have become increasingly commercialized …

In this comprehensive review, recent progress and developments on perfluorinated sulfonic-
acid (PFSA) membranes have been summarized on many key topics. Although quite well …

Manipulation of the conductive network is essential for the electromagnetic interference
(EMI) shielding performance of conductive polymer composites, which have broad …

The structure of the Nafion ionomer used in proton-exchange membranes of H2/O2 fuel cells
has long been contentious. Using a recently introduced algorithm, we have quantitatively …

A fundamental understanding of structure‐morphology‐property relationships of proton
exchange membranes (PEMs) is crucial in order to improve the cost, performance, and …

Perfluorinated sulfonic acid (PFSA) ionomers are the most widely used solid electrolyte in
electrochemical technologies due to their remarkable ionic conductivity with simultanous …

Hydrogen energy as the next‐generation clean energy carrier has attracted the attention of
both academic and industrial fields. A key limit in the current stage is the operation …

Perfluorosulfonic-acid (PFSA) ionomer membranes (most commonly Nafion®) are currently
the prototypical proton-exchange-membrane in polymer-electrolyte fuel cells (PEFCs), for …

Rapid improvements in polymer-electrolyte fuel-cell (PEFC) performance have been driven
by the development of commercially available ion-conducting polymers (ionomers) that are …

Using both scattering and microscopy techniques, we have characterized the complex
Nafion structure over a large range of length scales. Analysis of experimental data from dry …
