The membrane for PEMFC at high temperature was prepared from Polyimide containing Benzimidazole and mesoporous inorganic filler. And also organic-inorganic composite membrane from polyimide and mesoporous inorganic materials were synthesized. We investigated effects of the benzimidazole group of the polymer and mesoporous inorganic materials. The synthesis of polyimide containing benzimidazole 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) The conductivity depending on the temperature was analyzed with Impedence Analyzer (Autolab Impedence Analyzer). |
