Definitions

  • the flooding of the cathode (insufficient diffusion of oxygen within the reaction layer due to partial blockage of the pore system with liquid water) as well as the condensation of water in the GDL poses a problem since the flooding of the cathode is not only a problem limited performance but also has a negative impact on the life.
  • the graphite content of the microporous layer of the anodic GDL (15) is 50 to 90%.
  • PTFE Polytetrafluoroethylene hydrophobic. Microporous layers were coated onto the above-mentioned by knife coating by means of pasty carbon-PTFE dispersions. Carrier papers produced.
