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.
