Mixture comprising phosphonic acid containing vinyl, polymer electrolyte membranes comprising polyvinylphoshphonic acid and the use thereof in fuel cells |
摘要 |
Mixtures containing vinyl-containing phosphonic acid, polymer electrolyte membranes comprising polyvinylphosphonic acid and their use in fuel cells. The present invention relates to a proton-conducting polymer membrane based on polyvinylphosphonic acid obtainable by a process comprising the steps A) Mixing a polymer with vinyl-containing phosphonic acid, B) Forming a two-dimensional structure using the mixture according to step A) on a carrier, C) Polymerisation of the vinyl-containing phosphonic acid present in the two-dimensional structure according to step B). A membrane according to the invention may on account of its outstanding chemical and thermal properties be used in a wide range of applications and is particularly suitable as a polymer-electrolyte membrane (PEM) in so-called PEM fuel cells. |
