摘要： The electrochemical energy conversion system include an anode, a cathode, and a proton exchange membrane disposed between the anode and the cathode. The proton exchange membrane includes a polymer having a hard block polymer, a soft block polymer, and one or more hydrophilic functional groups attached to the soft block polymer. The glass transition temperature of the hard block polymer is higher than a glass transition temperature of the soft block polymer, such that the hard block polymer is non-elastic and the soft block polymer is elastic at a desired operating temperature. The hydrophilic functional groups are attached to the soft block polymer via a thiol-ene reaction to modify double bonds in the soft block polymer. The swellable functional groups are selectively connected to the soft domains of the block copolymers, so that when the membrane swells (under hydration or gas adsorption), the stress is effectively absorbed by the soft domain and the impact on overall mechanical properties is minor, resulting in more durable membranes.

摘要： The present invention addresses the problem of providing a crosslinked film and a hydrocarbon-based proton conducting solid electrolyte having a proton conductivity equal to that of a perfluorosulfonate ion exchange polymer. Disclosed as a means for solving this problem is a proton conducting polymer electrolyte which is composed of a sulfonated polyphenyl compound having a plurality of repeating units, and wherein two or more (for example, four or six) sulfonic groups are introduced into one repeating unit on average. The sulfonated polyphenyl compound may be a polymer or copolymer having a skeleton structure selected from among a polyaryl sulfide, a polyaryl ether, a polyarylsulfone, a polyarylketone and a polyaryl hexafluoroisopropylidene. A proton conducting solid polymer electrolyte membrane is able to be produced by shaping this proton conducting polymer electrolyte into a film form and crosslinking this proton conducting polymer electrolyte via sulfonic groups.
