  • Patent number: 8552076
    Abstract: Disclosed herein is a method of preparing a fused aerogel-polymer composite in which aerogel and an organic polymer is mixed in a dry state to adsorb polymer particles on the surface of the aerogel and are then subjected to thermal treatment, thus forming a polymer coating on the aerogel. The fused aerogel-polymer composite can be used for thermal insulation in a variety of applications. The fused aerogel-polymer composite exhibits high thermal insulation properties and superior physical strength and processability while still maintaining the properties of an aerogel that does not have a polymer coated on its surface.

  • Patent number: 8501370
    Abstract: A binder for an electrode of a fuel cell is a basic polymer including a nitrogen-containing functional group and a proton conductive polymer having a phosphoric acid impregnation capacity of 200 wt % or less. An electrode for a fuel cell includes the binder and a catalyst, and a fuel cell includes the electrode. The electrode is manufactured by mixing the binder, a catalyst, and a solvent; and coating the mixture on a carbon support and heat-treating the coated mixture. The binder has excellent proton conductivity by having a phosphoric acid impregnation capacity of 200 wt % or less, and has improved durability without membrane damage and micro-structural changes due to swelling, which occurs when PBI is used as a binder. Accordingly, an electrode including the binder has improved phosphoric acid retention capacity, and increased wetting velocity. Thus, a fuel cell having improved efficiency can be manufactured due to the improved proton conductivity and durability of the electrode.
