제목 | Cross-Linked benzoxazine-benzimidazole copolymer membranes for high temperature PEM fuel cell applications. |
초록 | The cross–linked copolymer membranes were fabricated by mixing poly[2,2’–(m–phenylene)–5,5’–bibenzimidazole] (PBI) with 6–fluoro-3-(pyridin–2–yl)-3,4-dihydro-2H-benzoxazine (pF) in N,N–dimethylacetamide via subsequent step–wise heating to 220 °C. The membranes were characterized after doped by phosphoric acid. The increases in high proton conductivity and cell perfomance were observed with the increasing amount of the bezoxazine. The cross-linked membranes showed larger operating voltage and long-term durability with much slower performance decay than those of commercially available PBI membranes. |
