In this study, behaviours of activated carbon\r\nnanofiber (ACNF), carbon nanofiber (CNF), polyacrylonitrile\/ carbon\r\nnanotube (PAN\/CNT), polyvinyl alcohol\/nanosilver (PVA\/Ag) in\r\nproton exchange membrane (PEM) fuel cells are investigated\r\nexperimentally. This material was used as gas diffusion layer (GDL)\r\nin PEM fuel cells. In this study, the electrical conductivities of\r\nnanofiber and nanofiber\/nanoparticles have been studied to\r\nunderstand their effects on PEM fuel cell performance. According to\r\nthe experimental results, the maximum electrical conductivity\r\nperformance of the fuel cell with nanofiber was found to be at\r\nPVA\/Ag (at UConn condition). The electrical conductivities of CNF,\r\nACNF, PAN\/CNT are lower for PEM. The resistance of cell with\r\nPVA\/Ag is lower than the resistance of cell with PAN\/CNT, ACNF,\r\nCNF.","references":"[1] Steven J. Hamrock and Michael A.
