The Gas Diffusion Layer (GDL) of fuel cell, are required to provide both delivery of reactant gases to
the catalyst layer and removal of water in either vapor or liquid form in typical PEMFCs. In this study, the fabrication of GDL containing Micro Porous Layer (MPL) made of the slurry of PVDF mixed with carbon black is investigated in detail. Physical properties of GDL containing MPL, such as electrical resistance, gas permeability and
microstructure were examined, and the performance of the cell using developed GDL with MPL was evaluated.
The results show that MPL with PVDF binder demonstrated uniformly distributed microstructure without large
cracks and pores, which resulted in better electrical conductivity. The fuel cell performance test demonstrates that
the developed GDL with MPL has a great potential due to enhanced mass transport property due to its porous
structure and small pore size.
