Investigation of Current Density Effect on Water Vapor Concentration Profile along PEMFC Channels by TDLAS

Investigation of Current Density Effect on Water Vapor Concentration Profile along PEMFC Channels by TDLAS

In this article, we applied tunable diode laser absorption spectroscopy (TDLAS) technique to measure variation of water vapor concentration in gas flow channels in an operating polymer electrolyte membrane fuel cell (PEMFC). TDLAS measurement offered an optical remote sensing to detect slight change...
