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.
