PROTON CONDUCTING MEMBRANE |
摘要 |
(Object) A proton conductive membrane capable of sufficient proton conductivity even at low humidities and low temperatures is provided. (Means for solution) The proton conductive membrane includes a copolymer including an ion conductive polymer segment (A) and an ion nonconductive polymer segment (B), the membrane absorbing water when it is soaked in 90°C water for 30 minutes of which the quantity of water showing freezing temperatures in the range of -30 to 0°C is 0.01 to 3.0 gbasedon 1 g of the copolymer. The copolymer has a structure in which main chain skeletons of the copolymer are covalently bound at aromatic rings thereof through binding groups. |
