Patent

CA 2478252

The invention relates to a proton conducting polymer membrane based on polyvinylphosphonic acid obtained by means of a method comprising the following steps: A) mixing a polymer with phosphonic acid containing vinyl, B) forming a flat structure by using the inventive mixture from step A) on a support, C) polymerisation of the vinylphosphonic acid present in the flat structure according to step B). The inventive membrane can be used in a variety of ways 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.

Membrane polymère conductrice de protons à base d'acide polyvinylphosphonique qui peut être obtenue par un procédé consistant (A) à mélanger un polymère avec de l'acide phosphonique contenant du vinyle, (B) à former une structure plate à l'aide du mélange obtenu à l'étape (A) sur un support et (C) à polymériser l'acide vinylphosphonique présent dans la structure plate obtenue à l'étape (B). En raison de ses excellentes propriétés chimiques et thermiques, la membrane selon la présente invention peut être utilisée dans de nombreuses applications et convient particulièrement en tant que membrane polymère (PEM) dans les piles à combustibles PEM.
