Situ Measurement of Water Vapor in PEMFC Using TDLAS

In Situ Measurement of Water Vapor in PEMFC Using TDLAS 

This water back-transport index is expressed as the normalized through-plane water flux from the cathode side to the anode side divided by the water generation rate at the cathode. Consequently, a 

As shown above, in-situ TDLAS measurements show its unique potential to investigate localized water transport in operating PEMFCs, leading to fundamental understanding on water management. It is also capable of monitoring localized phenomena with good temporal resolution.
