Small-angle scattering (SAS) is a technique that is able to probe the structural organization
of matter and quantify its response to changes in external conditions. X-ray and neutron …

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

The perfluorosulfonic acid (PFSA) proton exchange membrane (PEM) is the key component
for hydrogen fuel cells (FCs). We used in situ synchrotron scattering to investigate the PEM …

Ionomers are important to electrode function in energy conversion devices, such as fuel cells
and electrolyzers, as the catalyst‐binding nanometer‐thick films under confinement, which …

Although the properties of perfluorosulfonic acid (PFSA) membranes (10–100 s μm thick) in
proton exchange membrane fuel cells (PEMFCs) have been well studied for decades, the …

Copper-based membrane-electrode assemblies (Cu-MEAs) hold promise for increasing the
energy efficiency for the electrochemical reduction of CO2 to C2+ products, while …

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 …

Slot-die coating being compatible with the roll-to-roll technique has been regarded as a
promising tool for upscaling the manufacturing of organic solar cells (OSCs). However, there …

The dispersing solvent used for fuel cell catalyst ink preparation plays a vital role in
establishing the resulting morphology of the electrode layers, which in turn will impact the …

With lower site density and turnover frequency, platinum group metal (PGM)-free catalysts
based electrodes are often greater than 50 μm thick in order to increase performance across …
