Impact of the temperature variation on the thermal conductivity of gas diffusion layers for polymer electrolyte fuel cells
The purpose of this study is to evaluate the thermal conductivity of gas diffusion layers (GDLs) when subjected to different operating temperatures. The measurement apparatus is completely designed and the thermal conductivities are evaluated for five different GDL samples. The amount of catalyst material within the GDLs is also considered in the current study. Based on the obtained measurements,
