METHOD FOR IN-SITU PREPARATION OF POLYBENZIMIDAZOLE-BASED ELECTROLYTE MEMBRANE AND POLYBENZIMIDAZOLE-BASED ELECTROLYTE MEMBRANE PREPARED THEREBY |
摘要 |
Disclosed is a method for in-situ preparation of a polybenzimidazole-based electrolyte membrane, including: polymerizing a polybenzimidazole polymer in a solution; casting a solution containing the polymerized polymer onto a substrate and drying the solution in air to form a membrane; washing the dried membrane with water or alcohol; and allowing water or alcohol to evaporate from the membrane containing water or alcohol, while maintaining the shape of the membrane. The method for in-situ preparation of a polybenzimidazole-based electrolyte membrane allows easy preparation of a polybenzimidazole-based electrolyte membrane having a desired area without any complicated processes, and thus contributes to simplification of an overall process for fabricating a fuel cell.
