MEMBRANE STRUCTURE

摘要

A membrane, suitable for use in a fuel cell, wherein the membrane comprises: (a) a central region comprising an ion-conducting polymeric material; (b) a border region which creates a frame around the central region and which consists of one or more non-ion-conducting materials wherein at least one of the one or more non-ion-conducting materials forms a layer; wherein the non- ion-conducting material of the border region overlaps the ion- conducting polymeric material of the central region by 0 to 10mm in an overlap region, is disclosed.
