## Abstract This study introduces a novel strategy for enhancing the performance of polymer electrolyte fuel cells at high current densities by means of an advanced gas diffusion layer design. The incorporation of hydrophilic wicking agents into microporous layers of the cathode gas diffusion layer
Water flow through carbon cloth and carbon paper gas diffusion media used for polymer electrolyte membrane fuel cells treated with Teflon was measured. The gas diffusion layer (GDL) media are hydrophobic and it is necessary to apply pressure to force water to penetrate into the pores of these materi
## Abstract Water content in the membrane and the presence of liquid water in the catalyst layers (CL) and the gas diffusion layers (GDL) play a very important role in the performance of a PEM fuel cell. To study water transport in a PEM fuel cell, a twoโphase flow mathematical model is developed.
## Abstract A model fuel cell with a single transparent straight flow channel and segmented anode was constructed to measure the direct correlation of liquid water movement with the local currents along the flow channel. Water drops emerge through the largest pores of the GDL with the size of the d
