  • GAS DIFFUSION LAYER WITH IMPROVED ELECTRICAL CONDUCTIVITY AND GAS PERMEABILITY AND PROCESS OF MAKING THE GAS DIFFUSION LAYER
    Publication number: 20140205919
    Abstract: A gas diffusion layer contains a substrate formed of a carbon containing material and a micro porous layer. The gas diffusion layer can be obtained by dispersing carbon black with a BET surface area of at most 200 m2/g, carbon nanotubes with a BET surface area of at least 200 m2/g and with an average outer diameter of at most 25 nm and a dispersion medium at a shearing rate of at least 1,000 seconds?1 and/or such that, in the dispersion produced, at least 90% of all carbon nanotubes have a mean agglomerate size of at most 25 ?m. The dispersion is applied to at least one portion of at least one side of the substrate, and the dispersion is dried.
