POLYBENZIMIDAZOLE-BENZAMIDE COPOLYMER, PROCESS FOR PREPARING THE SAME, ELECTROLYTE MEMBRANE PREPARED THEREFROM AND PROCESS FOR PREPARING THE SAME |
摘要 |
The present invention relates to a novel polybenzimidazole-benzamide copolymer composed of the repeating units represented by formula 1 which is applicable to the electrolyte membrane of fuel cell and a preparation method of the same. The present invention also relates to an electrolyte membrane produced from the above copolymer of the invention and a preparation method thereof. The present invention further relates to a membrane-electrode unit for fuel cell containing the electrolyte membrane of the invention and a fuel cell system including the unit. The electrolyte membrane prepared by the polybenzimidazole-benzamide copolymer of the invention has improved proton conductivity, compared with the conventional polybenzimidazole polymer membrane, and has thermal and chemical stability in addition to the operating capacity in a wide temperature range. Wherein, x is 0.1~99.9. |
