Electrospinning is gaining popularity as a convenient and cost-effective technique for the fabrication of sub-micron diameter polymer fibers. Recently, nanofiber electrospinning has been used to fabricate high performance hydrogen/air fuel cell membranes and electrodes and for preparing anion-exchange membranes for alkaline fuel cells. A dual fiber method has been used successfully to prepare nanofiber composite proton-exchange and hydroxide-ion-exchange membranes with high conductivity and good mechanical properties. Similarly, electrospun polymer/particle nanofiber fuel cell electrodes have performed exceedingly well in lab-scale fuel cell tests. Electrospinning also can be used to make components for lithium ion batteries. This presentation will review and discuss: (1) experimental methods for fabricating and characterizing electrospun fuel cell and battery materials and (2) the performance and durability of these materials.
