What is it about?
In this paper, the Open Photoacoustic Cell (OPC) technique and Thermal Lens Spectrometry (TLS) are applied in order to determine a thermal parameter of great interest, the thermal diffusivity as a function of the water content in the Nafion® membranes.

Why is it important?
Since the nafion membrane is used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzes and as dryer and humidifier gases its important to know how the content the water affects the thermal diffusivity.
