The through-plane thermal conductivity of many components of a fuel cell, dry NafionĀ®, various diffusion medias and catalyst layers are studied. The thermal contact resistance between the diffusion media and a metal plate with respect to temperature and pressure was also determined. The measurements were made with a guarded heat flow meter device. The least accurate measurement was of the Toray carbon ...
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 ...
