Title:
CRYSTALLINE SULFONATED POLYIMIDE BLOCK COPOLYMER PROTON EXCHANGE MEMBRANE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/043009
Kind Code:
A1
Abstract:
A crystalline sulfonated polyimide block copolymer proton exchange membrane, a preparation method therefor, and use thereof, relating to the technical field of fuel cells. The chemical structural formula thereof is as shown in (I), in which the Ar1 group is an aromatic group comprising a naphthyl group, the Ar2 group is an aromatic group comprising at least one sulfonic group, x=5-100, m=1-200, and n=5-500. The preparation process is simple and is easy to achieve mass production; moreover, said proton exchange membrane has high proton conductivity and good durability, so that the power generation performance of the proton exchange membrane fuel cell is not easily affected by external humidification conditions, and still has good power generation performance under high-temperature and low-humidity conditions.
