High-Performing and Stable Membrane Electrode Assemblies Based on Fluorine-Doped Tin Oxide Catalysts

Abstract To improve the iridium utilization on proton exchange membrane water electrolysers (PEMWEs), a new support based on fluorine-doped tin oxide (FTO) nanoparticles was developed, characterized, and assessed for the anode side. This approach utilizes a sol–gel method combine...

Boosting Reactant Transport in Low-Pt-Loaded Proton Exchange Membrane Fuel Cells via a Tailored Ionomer Assembly Strategy

Abstract Reducing the Pt loading of proton exchange membrane fuel cells (PEMFCs) is a crucial research focus to advance their commercial application. In conventional membrane electrode assemblies (MEAs), the random and inhomogeneous ionomer distribution significantly restricts bo...
