To prepare PBI-Copolymer (Polybenzimidazole) and mesoporous inorganic filler composite membranes for PEMFC (Polymer electrolyte membrane Fuel Cell), 3,3’-diaminobenzidine was synthesized with pyridine-2,5-dicarboxylic acid and Terephtalic acid. Polyphosphoric acid was used as solvent. And also organic-inorganic composite membranes from PBI-Copolymer and mesoporous inorganic materials were synthesized. The mesoporous inorganic materials were containing specific metal ions. Amount of metal ions of mesoporous inorganic filler was confirmed by XRF. |
