Description
One of the current approaches in material development for fuel cells is the use of nanofibres.This approach offers advantages, particularly with regard to the high surface area and
porosity of the nanofibres. The electrospinning process is used for processing a polymer
liquid that is stretched by electrostatic force into a nanoscale structure from the nozzle to
the collector at the required distance [3]. An additional advantage of the electrospinning
technique is its ability to fabricate both the electrode and the membrane. CEET has
developed composite membranes based on nanofibre structures for anion exchange
membrane fuel cells. Polymer-based composite membranes with high OH conductivity,
excellent mechanical integrity and good chemical stability were successfully fabricated and
characterised [4][5]. The electrode fabrication method has also been revisited based on
materials and techniques, including nanofibres, compared to other methods in terms of
cathode loading, Pt utilisation and peak power density [6].
Even though it is a sophisticated tool, it should be kept in mind that electrospinning is
controlled by a variety of complex parameters. It is necessary to investigate how the
influencing factors affect the nanofibre structure [7][8]. Aligned nanofibres are seen as a
potential improvement. The electrospinning machine used (Tong Li-Tech, TL -Pro) has
different modes of rotating collectors with an adjustable ratio speed. By optimising the
nanofibre parameters, the nanofibre can be tailored to change its pattern.
