Outline of Final Research Achievements |
In this study, the laser spectroscopy system for in-line monitoring of water vapor concentration in gas channel of fuel cell was developed based on fiber-optic cavity ring-down spectroscopy (CRDS) technique. Furthermore, the numerical simulation model for analyzing water and oxygen transport in gas diffusion electrode was established by taking into account porous structure, and the liquid water behavior and oxygen diffusion inside a cathode electrode of PEFC were elucidated.
