摘要： An automated roll to roll method of making a fuel cell roll good subassembly is described wherein an elongated first subgasket web having a plurality of apertures is moved relative to a plurality of individual electrolyte membranes, each individual electrolyte membrane having a center region. The individual electrolyte membranes are aligned with the first subgasket web so that a center region of each electrolyte membrane is aligned with an aperture of the first subgasket web and the individual electrolyte membranes are attached to the first subgasket web.

摘要： The present disclosure relates membrane-electrode assemblies and electrochemical cells and liquid flow batteries produced therefrom. The membrane-electrode assemblies include a first porous electrode; an ion permeable membrane, having a first major surface and an opposed second major surface; a first discontinuous transport protection layer disposed between the first porous electrode and the first major surface of the ion permeable membrane; and a first adhesive layer in contact with the first porous electrode and at least one of the first discontinuous transport protection layer and the ion permeable membrane. The first adhesive layer is disposed along the perimeter of the membrane-electrode assembly. The first porous electrode and first discontinuous transport protection layer, without the presence of the first adhesive layer, are not an integral structure and the membrane-electrode assembly is an integral structure

摘要： 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.

摘要： A fuel cell roll good subassembly is described that includes a plurality of individual electrolyte membranes. One or more first subgaskets are attached to the individual electrolyte membranes. Each of the first subgaskets has at least one aperture and the first subgaskets are arranged so the center regions of the individual electrolyte membranes are exposed through the apertures of the first subgaskets. A second subgasket comprises a web having a plurality of apertures. The second subgasket web is attached to the one or more first subgaskets so the center regions of the individual electrolyte membranes are exposed through the apertures of the second subgasket web. The second subgasket web may have little or no adhesive on the subgasket surface facing the electrolyte membrane.
