摘要： A reinforced ion-conducting membrane comprises a planar reinforcing component which comprises a porous polymer material; an ion-conducting component embedded in at least a region of the planar reinforcing component, which ion-conducting component comprises an ion-conducting polymer material; and linking groups which are chemically bonded to both the planar reinforcing component and the ion-conducting component. The reinforced ion-conducting membrane is useful as the membrane in a membrane-electrode assembly for example as used in fuel cells.
