英文摘要 | a sulfonated polyimide (spi)/ptfe reinforced membrane was synthesized by impregnating ptfe (porous polytetrafluoroethylene) membrane with a spi/dmso solution. the resulting composite membrane was mechanically durable and quite thin relative to traditional perfluorosulfonated ionomer membranes (pfsi). we expect the ptfe to restrict the swelling and dimensional change of the spi when it is immersed into water. and the reinforcement with ptfe can increase the hydrolysis stability of the spi due to the low swelling and low dimensional change. from ex-situ testing and a short term fuel cell "life" test, we conclude that the ptfe reinforced sulfonated polyimide had a higher hydrolytic stability than pure sulfonated polyimide. the thin spi/ptfe membrane showed comparable fuel cell performance with the commercial nre-212 membrane with h(2)/o(2) at 80 degrees c under fully humidified conditions. the chemically modified membrane with nation layer showed good stability in a 120 h fuel cell test.
