Jigsaw Puzzle Inspired Patterning of Gas Diffusion Layers for Enhanced Water Management in Polymer Electrolyte Fuel Cells. [PDF]
Adv Sci (Weinh)A novel jigsaw‐inspired method introduces patterned hydrophilic domains into gas diffusion layers (GDLs) to enhance water management in polymer electrolyte fuel cells (PEFCs). This scalable technique improves high‐current performance by separating water and gas pathways, offering a promising advance for hydrogen‐based energy systems.

Nitrogen-Containing Carbon-Encapsulated Platinum Electrocatalysts Supported by Single-Walled Carbon Nanotubes for Polymer Electrolyte Fuel Cells. [PDF]
Small MethodsPt/N‐SWCNT electrocatalyst, synthesized via a solution plasma method, exhibits enhanced stability of cathode catalyst in PEFC. Encapsulated Pt nanoparticles within nitrogen‐containing carbon shells improve durability and show only 39.5% power density loss after 8000 AST cycles of potential wave (1.0 to 1.5 V).

Drastic Enhancement of Activity and Durability for Oxygen Reduction Reaction by Melamine Modification for Platinum Nanocluster-Loaded Electrocatalysts. [PDF]
Small SciWe developed 1 nm platinum (Pt) nanoclusters whose mass activity and durability were enhanced 6.37 and 2.5 times, respectively, via melamine modification. After durability tests, activity remained 11.0 times higher than commercial catalysts. This strong Pt–melamine interaction stabilizes small clusters, offering a pathway to significantly reduce Pt ...
