  • Publication number: 20140308600
    Abstract: New polymeric networks bearing benzimidazole units have been prepared. These polymeric networks will combine high proton conductivity, superior mechanical properties and thermal and oxidative stability due to the existence of polar benzimidazole groups and the presence of the unique polymeric architecture. The prepared polymer networks can be used in the catalyst ink of the electrodes in high temperature PEM fuel cells.

  • Patent number: 8247521
    Abstract: New multifunctional aromatic copolymers bearing pyridine or pyrimidine units either in the main chain or side chain and single wall carbon nanotubes or multi wall carbon nanotubes as side chain pendants have been prepared. These multifunctional materials will combine both high proton and electrical conductivity due to the existence of polar pyridine or pyrimidine groups and carbon nanotubes within the same chemical structure. The prepared multifunctional materials can be used in the catalyst ink of the electrodes in high temperature PEM fuel cells.
