The recent release of hydrogen economy roadmaps for several major countries emphasizes
the need for accelerated worldwide investment in research and development activities for …

Alkaline‐based electrochemical devices, such as anion exchange membrane (AEM) fuel
cells and electrolyzers, are receiving increasing attention. However, while the catalysts and …

As substantial progress has been made in improving the performance of anion exchange
membrane fuel cells (AEMFCs) over the last decade, the durability of AEMFCs has become …

The most critical challenge for the large‐scale commercialization of proton exchange
membrane fuel cells (PEMFCs), one of the primary hydrogen energy technologies, is to …

This work demonstrated a robust, scalable cell architecture for electroreduction of CO2
(CO2R). An up to 90% faradaic efficiency for the conversion of CO2R to formate at 500 …

Perfluorinated‐sulfonic‐acid‐based ionomers (PFSAs) are still the material of choice for
electrochemical energy devices such as proton‐exchange membrane fuel cells or water …

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 …

The structure of a catalyst layer (CL) significantly impacts the performance, durability, and
cost of proton exchange membrane (PEM) fuel cells and is influenced by the catalyst ink and …

For proton exchange membrane fuel cells to be cost‐competitive in light‐and heavy‐duty
vehicle applications, their Pt content in the catalyst layers needs to be lowered. However …

Non-fluorinated hydrocarbon ionomers feature distinct technical, cost, and environmental
advantages over incumbent perfluorinated sulfonic acid (PFSA)-based ionomers: they offer …
