Patent

CA 2400027

The invention relates to a membrane, in particular, a membrane for use in a methanol fuel cell. The inventive membrane comprises complexing agents for cations and, therefore, functions like an anion exchanger. In a particular embodiment, the membrane comprises complexing agents selected from the group of crown ethers, cryptates, or of cryptate-like compounds based on carbon cyclic compounds or silicon cyclic compounds.

L'invention concerne une membrane, notamment une membrane s'utilisant dans une pile à combustible au méthanol. Cette membrane présente des agents complexants pour cations et fait ainsi office d'échangeur d'anions. Dans un mode de réalisation préféré, la membrane présente des agents complexants du groupe des éthers couronnes, des cryptats ou des composés analogues aux cryptats, à base de composés cycliques de carbone ou de silicone.
