• D204 Measurement of Liquid Water Behavior in Gas Diffusion Layer with Perforation Structure of PEFC

抄録

In order to alleviate liquid water flooding in polymer electrolyte fuel cells (PEFCs), it is essential to design the optimum electrode structure on cathode side. In this study, the dynamic behavior of water droplets in an operating PEFC was optically visualized using a high-resolution microscope, and the effect of perforation structure of cathode gas diffusion layer (GDL) on the liquid water transport and cell performance was investigated. The perforation holes were cut in the porous GDL by electric discharge machining and micro-drilling technique. It is noted that the hydrophobic perforation hole machined by the micro-drilling technique effectively promotes the liquid droplet removal from the cathode GDL.
