| Outline of Final Research Achievements |
In this study, the laser gas analyzer with a fiber-optic probe was firstly developed based on tunable diode laser absorption spectroscopy (TDLAS) to measure reactive gas concentrations in flow channels of fuel cells at high speed and high sensitivity, and was applied to the direct monitoring of water concentration in the cathode channel of a working PEFC. Furthermore, the numerical simulation model for analyzing mass transport in gas diffusion electrodes was established by taking into account porous structure, and the liquid water behavior and oxygen diffusion at the cathode electrode/electrolyte interface of a PEFC were elucidated.
