Abstract:

Fabrication methods for making a gas diffusion layer incorporating a gasket (GIG) fuel cell subassemblies via roll-to-roll processes are described. A material processable by one or both of heat and pressure having spaced apart apertures is transported to a bonding station. A first gasket layer having gas diffusion layers arranged in relation to spaced apart apertures of a first gasket layer is transported to the bonding station. The heat/pressure processable material is aligned with the first gasket layer and the gas diffusion layers. At the bonding station, the heat/pressure processable material is bonded to the first gasket layer and the gas diffusion layers. After bonding, the heat/pressure processable material forms a second gasket layer that attaches the gas diffusion layers to the first gasket layer.

US Classification:

429535, 429479, 429507, 427115

Abstract:

A method and apparatus for making fuel cell components via a roll to roll process are described. Spaced apart apertures are cut in first and second gasket webs that each include adhesives. The first and second gasket webs are transported to a bonding station on conveyers. A membrane web that includes at least an electrolyte membrane is also transported to the bonding station. At the bonding station, a gasketed membrane web is formed by attaching the first and second gasket webs to the membrane web. The first gasket web is attached to a first surface of the membrane web via the adhesive layer of the first gasket web. The second gasket web is attached to a second surface of the membrane web via the adhesive layer of the second gasket web.

International Classification:

F16J 15/02

US Classification:

277654

Abstract:

A gas diffusion layer incorporating a gasket (GIG) is described along with assemblies incorporating the GIG subassembly. Processes for making the GIG and membrane electrode assemblies (MEAs) incorporating the GIG are also described. A GIG subassembly includes a gas diffusion layer (GDL) and a gasket bonded to the GDL. The gasket includes a first gasket layer and a second gasket layer. The second gasket layer is formed of a gasket material in contact with the first gasket layer and the GDL. The gasket material of the second gasket layer bonds the GDL to the first gasket layer. An adhesive layer, and optionally a removable adhesive liner, is disposed on a surface of the first gasket layer opposite the second gasket layer. In some MEA configurations, the GDL is disposed within an aperture in the first gasket layer.

Abstract:

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
