Experimental Investigation of Proton Exchange Membrane Fuel Cells Operated with Nanofiber and Nanofiber/Nanoparticle
Nanofibers are defined as fibers with diameters less
than 100 nanometers. In this study, behaviours of activated carbon
nanofiber (ACNF), carbon nanofiber (CNF), polyacrylonitrile/ carbon
nanotube (PAN/CNT), polyvinyl alcohol/nanosilver (PVA/Ag) in
proton exchange membrane (PEM) fuel cells are investigated
experimentally. This material was used as gas diffusion layer (GDL)
in PEM fuel cells. In this study, the electrical conductivities of
nanofiber and nanofiber/nanoparticles have been studied to
understand their effects on PEM fuel cell performance. According to
the experimental results, the maximum electrical conductivity
performance of the fuel cell with nanofiber was found to be at
PVA/Ag (at UConn condition). The electrical conductivities of CNF,
ACNF, PAN/CNT are lower for PEM. The resistance of cell with
PVA/Ag is lower than the resistance of cell with PAN/CNT, ACNF,
