Abstract:
1. A method of making gas diffusion layer incorporating gasket (GIG) fuel cell subassemblies via a roll-to-roll process, comprising: transporting a material processable by one or both of heat and pressure and having spaced apart apertures to a bonding station; transporting a first gasket layer having gas diffusion layers arranged in relation to spaced apart apertures of the first gasket layer to the bonding station; aligning the heat/pressure processable material with the first gasket layer and the gas diffusion layers; and at the bonding station, bonding the heat/pressure processable material to the first gasket layer and the gas diffusion layers, the heat/pressure processable material, after bonding, forming a second gasket layer that attaches the gas diffusion layers to the first gasket layer, wherein each GIG fuel cell subassembly consists essentially of a gas diffusion layer, a first gasket layer, a second gasket layer, an adhesive layer, and optionally, a removable liner.
