Research Abstract |
In this study, the laser spectroscopy system for high time-resolution and high-sensitive quantitative measurement of water vapor in fuel cell was developed using fiber-optic cavity ring-down(CRD) spectroscopy. Furthermore, the concentration of water vapor generated in an operating polymer electrolyte fuel cell(PEFC) was monitored in line with this loop-type CRD spectroscopy system. It was found that the water vapor concentration in the cathode exhaust gas increases with an increase in current density
