Zusammenfassung:The present disclosure relates to electrode assemblies, membrane-electrode assemblies and electrochemical cells and liquid flow batteries produced therefrom. The electrode and membrane-electrode assemblies include (i) a porous electrode having a first major surface with a first surface area, Ae, an opposed second major surface and a plurality of voids; (ii) a discontinuous transport protection layer, comprising polymer, disposed on the first major surface and having a cross-sectional area, Ap, substantially parallel to the first major surface; and (iii) an interfacial region wherein the interfacial region includes a portion of the polymer embedded in at least a portion of the plurality of voids, a portion of the porous electrode embedded in a portion of the polymer or a combination thereof; and wherein 0.02Ae≤Ap≤0.85Ae and the porous electrode and discontinuous transport protection layer form an integral structure. The disclosure further provides methods of making the electrode assemblies and membrane-electrode assemblies.
