| Research Abstract |
In this study, the relationship between behavior of electrolytemembranes in polymer electrolyte fuel cell (PEFC) and cell performance was investigated.In-situ confocal micro-Raman spectroscopy was used to probe the water distribution inthe electrolyte membranes in PEFC under various cell-operating conditions. The waterdistribution in the electrolyte membranes can be understood as a balance amongback-diffusing water produced from the cathode, electro-osmotic drag, and water removalvia the gas diffusion layer. Furthermore, the water distribution was depended on phaseseparated structure of the electrolyte membrane.
