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： Described herein are stable hydroxide ion-exchange polymers and devices including the stable hydroxide ion-exchange N polymers. The polymers include ionenes, which are polymers that contain ionic amines in the backbone. The polymers are alcohol-soluble and water-insoluble. The polymers have a water uptake and an ionic conductivity that are correlated to a degree of N-substitution. Methods of forming the polymers and membranes including the polymers are also provided. The polymers are suitable, for example, for use as ionomers in catalyst layers for fuel cells and electrolyzers.

摘要： A manufacturing method of a proton exchange membrane is provided, which includes the steps as follows. The hydroxyl groups are disposed on the surface of a substrate by a hydrophilic treatment. The hydroxyl groups on the substrate are chemically modified with a coupling agent by a sol-gel process. The substrate is exposed to an amino acid with a phosphonate radical so that the amino acid containing a phosphonate radical can be chemically bonded with the coupling agent. The chemically bonded substrate is immersed in phosphoric acid for absorbing the phosphoric acid. The substrate blended with the phosphoric acid is placed between at least two leak-proof films for the purpose of preventing the leakage of the absorbed phosphoric acid. The proton exchange membrane manufactured by this method enable to retain the phosphoric acid in organic/inorganic complex form and micron/nano complex pore size.

摘要： A method is provided to fabricate an electrolyte membrane. The membrane has an asymmetric structure and is a polybenzimidazole membrane doped with phosphoric acid. The asymmetric structure comprises a dense layer and a porous layer. The content of phosphoric acid introduced into the polybenzimidazole membrane reaches 20 phosphoric acid molecules per polymer repeating unit.
