Manufacturers integrate these catalysts in complex assemblies called catalyst layers ... thickness of a porous polymer layer on the catalysts called ionomer. Ionomer thickness strongly influences ...

In the GDE, the catalyst layer (CL) is the main place for the catalytic reaction, which normally contains the catalyst, the catalyst carrier, and the ionomer. The preparation of CLs by ink-based ...

To improve stability, the team also looked at what would happen if they added a polymer called Nafion to the Fe-N-C catalyst. Nafion is a commonly used ionomer, a stable, highly conductive polymer ...

The researchers were able to analyze the electronic structure of this catalyst material with the addition of the ionomer Nafion ... ve uncovered an additional layer of complexity in this system.

“Although we know copper is the best catalyst for ... Schematic of a two-layer coating of films, called ionomers, on top of a copper surface. The negatively charged ionomer, Nafion, raises ...

By enabling potassium to adhere to the catalyst surface, this method minimizes direct contact with the ionomer, potentially reducing the cost of hydrogen production. The findings were published ...

A recent article in Nature Communications examined interactions between ionomers and catalysts in proton exchange membrane ...
