Abstract
The invention includes a reinforced membrane-seal assembly that comprises a reinforcing component, ion-conducting material, and seal material. The reinforcing component comprises a central region comprising a plurality of apertures extending from a first surface to a second surface of the reinforcing component, the central region having a first aperture area density; an inner peripheral border region surrounding the central region, where the inner peripheral border region is devoid of apertures; and an outer peripheral border region comprising a plurality of apertures extending from the first surface to the second surface of the reinforcing component, the outer peripheral border region having a second aperture area density. The outer peripheral border region surrounds the inner peripheral border region. The ion-conducting material at least partially fills each aperture in the central region of the reinforcing component and seal material fills each aperture in the outer peripheral border region of the reinforcing component.
