Preparation and their Properties of PBI and Mesoporous Inorganic Filler Composite Membranes for Fuel Cell Application |
| 초록 |
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. Composite membranes were doped with phosphoric acid (H3PO4). The synthesis of 2,5-PBI was confirmed by a Fourier Transform Infrared Spectroscopy (FT-IR, DIGILAB Co.). We also investigated thermal stability using Thermal Gravimetric Analysis (TGA, TA instrument, Q-50) for the composite PBI membranes. The ion conductivity depending on the temperature was measured with an Impedance analyzer (Autolab Impedence Analyzer), and interpreted as a function of the acid content and the weight percent of porous inorganic materials. |
