Synthesis of polybenzimidazoles for the PEM fuel cells |
| 초록 |
Acid-doped polybenzimidazole (PBI) membranes have been studied intensively because they can be used for the applications in the high temperature PEM fuel cells. This study deals with the synthesis of new PBIs that have bulky groups in the side chain for the fuel cell membrane applications. These polymers were synthesized from the solution polymerization of the dicarboxylic acid derivatives containing bulky moieties and the synthesis of the polymers was confirmed by IR spectroscopy. The thermal stability of the polymers was tested using Thermogravimetic analysis (TGA). Theses polymers were stable up to 400 oC. |
