Abstract: An electrochemical cell comprising a layered structure, the layered structure comprising at least a first layer and a second layer. The first layer and the second layer are arranged adjacent to each other and form a first interface, wherein the first interface comprises a first plurality of elongated nanostructures connected to a first surface of the first layer facing the second layer, and a second plurality of elongated nanostructures connected to a second surface of the second layer facing the first layer. The first plurality of elongated nanostructures and the second plurality of elongated nanostructures are mechanically entangled.

Abstract: A separator element arrangement for an electrochemical cell is presented. The separator element arrangement comprises a separator element and a diffusion layer arranged adjacent to the separator element. The separator element comprises a plurality of elongated nanostructures. At least some of the elongated nanostructures are arranged to connect the separator element to the diffusion layer by extending into the diffusion layer.
