To prepare polybenzimidazole (PBI) and mesoporous inorganic filler composite membranes for PEMFC (Polymer electrolyte membrane Fuel Cell), 3,3’-diaminobenzidine was synthesized with pyridine-2,5-dicarboxylic acid. Polyphosphoric acid was used as solvent. And also organic-inorganic composite membranes from PBI and mesoporous inorganic materials were synthesized. The mesoporous inorganic materials were containing specific metal ions. we changed Si/metal ratio of mesoporous inorganic materials. Composite membranes were doped with phosphoric acid (H3PO4). |
