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 ...
A novel technique was used in this research article, to introduce a hybrid mesh to a polymer composite within bipolar plates, for proton exchange membrane fuel cells (PEMFCs). The mesh added was copper or aluminum based, to allow for an increased thermal conductivity of the PEMFCs. Experimental testing confirms this theory, as the copper-meshed hybrid polymer composite showed a thermal conductivity of 30.0 W/mK, while the aluminum-meshed hybrid polymer composite ...
