Patent

CA 2551687

An ion-conducting polymer wherein at least 80% of the repeat units comprise an ion-conducting region and a spacer region is disclosed. The ion-conducting region has an aromatic backbone of one or more aromatic groups, wherein at least one ion-conducting functional group is attached to each aromatic group. The spacer region has an aromatic backbone of at least four aromatic groups, wherein no ion-conducting functional groups are attached to the aromatic backbone. The polymer is suitable for use as a fuel cell membrane, and can be incorporated into membrane electrode assemblies.

Polymère conducteur d'ions dans lequel au moins 80 % des unités répétées comprend une zone conductrice d'ions et une zone d'espacement. La zone conductrice d'ions possède un squelette aromatique d'un ou de plusieurs groupes aromatiques, au moins un groupe fonctionnel conducteur d'ions étant attaché à chaque groupe aromatique. La zone d'espacement possède un squelette aromatique d'au moins quatre groupes aromatiques, aucun groupe fonctionnel conducteur d'ions n'étant attaché à ce squelette aromatique. Ce polymère peut être utilisé de façon adéquate en tant que membrane de pile à combustible et peut être incorporé dans des ensembles d'électrodes à membrane.
