Abstract:
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.
