Surface-pattern engineering is a key strategy for fabricating high-performance Nafion membranes for fuel cells, with single-scale and multiscale patterned structures believed to improve membrane electrode assembly performance. The effects of different patterned structures on the construction and performance of fuel cells have been extensively studied, highlighting the importance of surface pattern engineering in membrane development for fuel cell applications.
Surface-pattern engineering, as a key strategy to fabricate high-performance Nafion membranes for fuel cells, plays an important role in surface functionalization of the membrane, optimization of the three-phase boundary, water management, proton transport, etc. Considerable efforts have been dedicated to developing advancedpatterned Nafion membranes with single-scale (nanoscale or microscale) and multiscale-patterned structures which are believed to improve the performance of membrane electrode assemblies (MEAs) for fuel cells. In this review, the recent progress in surface-patterned Nafion membranes (SPNMs) equipped with single-scalepatterned structures (including nanostructured and microstructured Nafion membranes) is firstly highlighted. The structural features and construction methods of SPNMs are discussed in detail. The effects of single-scale SPNMs on the construction and performance of fuel cells are also analyzed. Followed is an overview of the recent advances in fabricating multiscale SPNMs based on different strategies with a specific introduction on the membrane related effects on fuel cells. Finally, the future development direction and certain perspectives on the current issues of SPNMs are presented.
