  • Novel Polymer Networks Based on the Benzimidazole Moiety for High Performance Polymer Electrolyte Membrane Fuel Cells
    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.
