MIXTURE COMPRISING SULPHONIC ACID CONTAINING VINYL, POLYMER ELECTROLYTE MEMBRANE COMPRISING POLYVINYLSULPHONIC ACID AND THE USE THEREOF IN FUEL CELLS

摘要

The invention relates to a proton conducting polymer membrane based on polyvinylsulphonic acid obtained by a method comprising the following steps: A) mixing a polymer with sulphonic acid containing vinyl, B) forming a flat structure by using the inventive mixture from step A) on a support, C) polymerisation of the vinylsulphonic acid present in the flat structure according to step B). The inventive membrane can be applied in a varied manner on account of the excellent chemical and thermal properties thereof and is particularly suitable for use as a polymer-electrolyte-membrane (PEM) in PEM-fuel cells.
