Spectroscopic Monitoring of Energy Systems (Calvin W. Rice Lecture)

A review is presented for monitoring of chemical species in flames and plasmas used for energy systems. The monitoring systems studied in our group include the followings. 1. Developments and applications of planar laser induced fluorescence spectrometry (PLIF) using isotope effect and laser-induced plasma spectrometry (LIPS) for two-dimensional combustion analyses. 2. Development of direct measurements of chemical species during combustion by coupling flames and mass spectrometers. 3. Development of in-situ monitoring of polymer electrolyte fuel cells by near infrared spectrometry (NIR).
