제목 Development of Novel Polybezoxazine-Polybenzimidazole Electrolyte membrane for Fuel Cell at Elavated Temperature.
초록 New phosphoric acid-doped cross–linked benzoxazine–benzimidazole copolymer membranes for elevated temperature polymer electrolyte membrane fuel cells (PEMFCs) were fabricated. The cross–linked copolymer membranes were prepared by mixing poly[2,2’–(m–phenylene)–5,5’–bibenzimidazole] (PBI) with 3–phenyl–3,4–dihydro–6–tert–butyl–2H–1,3–benzoxazine (pBUa), followed by subsequent heating to 220 °C and even large-sized films could be easily prepared. A cell made of cross-linked membranes exhibited high proton conductivity and long-term durability compared to PBI membranes.
