POLYBENZIMIDAZOLE-BASE COMPLEX, METHOD FOR PRODUCING IT, ELECTROLYTE MEMBRANE FOR FUEL CELL, FUEL CELL, AND CROSSLINKED PRODUCT OF POLYBENZOXAZINE-BASED COMPOUND

摘要

PPROBLEM TO BE SOLVED: To provide a polybenzimidazole-base complex excellent in thermal stability and conductivity, a method for producing the polybenzimidazole-base complex, an electrolyte membrane for a fuel cell, a fuel cell, and a crosslinked product of the polybenzoxazine-based compound. PSOLUTION: In this polybenzimidazole-base complex comprising a polybenzimidazole-based material and a base, no peak corresponding to NH of an imidazole ring of the polybenzimidazole-based material does not appear at a chemical shift of 12-15 ppm. The polybenzimidazole-base complex is excellent in thermal stability and conductivity. PCOPYRIGHT: (C)2009,JPO&INPIT
