The invention provides the proton-conductive films that under low humidity, low temperature, also has enough proton conductivities.This proton-conductive films comprises segmented copolymer, the ionic conductivity polymer segment (A) of this segmented copolymer and the main chain backbone of nonionic conducting polymer segment (B) have by conjugated group the covalently bound structure of aromatic nucleus, and it is characterized in that: (i) kenel of this film has micro phase separation structure; (ii) ionic conductivity polymer segment (A) forms external phase. |
