Nanofiber/Nanoparticle Electrodes for Ultra‐low Platinum Fuel Cells via Simultaneous Foam Electrospinning and Electrospraying |
![]() In this study, we developed a new technique, simultaneous foam electrospinning and electrospraying (FE/E), that produces nanofiber/nanoparticle electrodes at higher production rates compared to needle‐based electrospinning and electrospraying (E/E). Herein, the nanofiber amount was precisely controlled by applying various voltages on the foam electrospinning process at a fixed platinum (Pt) loading, which enables an exclusive investigation into the impact of ionomer nanofiber on fuel cell performance at ultra‐low Pt loadings for proton exchange membrane fuel cells. The results show that fuel cell performance is strongly dependent on ionomer nanofiber content. At 0. |

A comparative fractographic analysis for the effect of polymeric nanofiber reinforcements on the tensile behavior of multi-layered epoxy nanocomposites
This study presents a comparative investigation into the effects of four different nanofibers—PA66, PStX, PAN, and PVB—on the mechanical performance and failure mechanisms of epoxy adhesive films. These nanofiber‐reinforced adhesive layers were manufactured via a dry‐reinforcement resin film infusion method and tested under uniaxial tensile loading. Mechanical results showed that PA66 and PStX nanofibers improved tensile strength by up to 25%, primarily by mitigating crack initiation at free edges and promoting effective fiber–matrix bonding. In contrast, PAN nanofibers induced micro‐cracks at the fiber–resin interface, amplifying crack coalescence and reducing strength by 25%. 03/01/2025
