The interface between the ionomer and catalyst can be engineered by tuning the interactions through surface functionalization of carbon supports of catalysts. Attractive interactions can enhance the performance, while repelling interactions can hinder the performance.
This work presents a one-dimensional continuum modeling approach to investigate various cell architectures used for electrochemical conversion of CO2 to formate/formic acid.
Ionomeric binders: integrating multidisciplinary advances to guide polymer electrolyte fuel cell development.
This review summarizes proton, water, and oxygen transport in ionomers of PEMFCs and highlights design strategies to optimize the three-phase boundary, enhancing mass transport, performance, and future prospects.
Significant performance enhancement in nanofiber-based PEMFCs featuring highly O2 permeable ionomer films, highly proton-conductive ionomer fibers, and increased active sites.
