In this paper, a new method is proposed for measuring the through plane thermal conductivity of two catalyst layers of different thicknesses by the guarded heat flow meter (GHF) method, and the transient plane source method (TPS). These catalyst layers were made from two catalyst-coated substrates. The effects of pressing, and hot pressing the layers were also studied and shown to have ...
This thesis looked at the relationship between thermal conductivity and compression and saturation in three different fuel cell diffusion media (DM). The stress-strain relationship of the materials was investigated using an optical microscope, and thermal conductivity was measured by a thermal constants analyzer. A theoretical model of the maximum through-plane thermal conductivity was developed as a function of compression and saturation....
