NOVELTY - Continuous production of a multiple layer web of fuel cell material involves laminating two webs, each comprising bonding material and having spaced apart windows, to two surfaces of a web comprising a fuel cell membrane. Two active regions of the membrane web are positioned within the respective bonding material windows. Fluid transport layer material portions is laminated to the active regions of the respective two surfaces of the membrane web, each of the fluid transport layer material portions contacting the bonding sites of the respective two windows.    USE - For continuous production of multiple layer web of fuel cell material for roll-good or singulated fuel cell sub-assembly (e.g. membrane electrode assembly) for use with and between a pair of flow field plates or between gasket layers, useful for producing multiple layer fuel cell assemblies (e.g. proton exchange membrane fuel cell assemblies e.g. for automobiles, or direct methanol fuel cell) as a unitized fuel cell assembly.    ADVANTAGE - The method provides for automated fabrication of multiple layer fuel cell assemblies and sub-assemblies in roll-good form in a continuous manufacturing process. The roll-good membrane film material becomes more stable for continuous membrane processing due to the tougher gasket material attached to it. The bonding material exposed at the edge of active area, seals gases from leaking through the FTL of the fuel cell assembly.    DETAILED DESCRIPTION - Continuous production of a multiple layer web of fuel cell material comprises cutting a first web comprising bonding material to produce spaced apart first windows in the first web, the first windows comprising bonding sites provided along a periphery of the first windows; cutting a second web comprising bonding material to produce spaced apart second windows in the second web, the second windows comprising bonding sites provided along a periphery of the second windows; providing a web comprising a fuel cell membrane having active regions disposed on respective first and second surfaces of the membrane web; laminating a first surface of the first bonding material web to the first surface of the membrane web so that the active regions of the first surface of the membrane web are positioned within the first windows; laminating a first surface of the second bonding material web to the second surface of the membrane web, so that the active regions of the second surface of the membrane web are positioned within the second windows; and laminating fluid transport layer (FTL) material portions cut from fourth and fifth webs comprising FTL material to the active regions of the respective first and second surfaces of the membrane web, each of the FTL material portions contacting the bonding sites of the respective first and second windows. INDEPENDENT CLAIMS are included for:    (1) a method of continuously producing multiple layer fuel cell assemblies;    (2) an apparatus for continuously producing multiple layer web of fuel cell material;    (3) a fuel cell assembly; and    (4) a fuel cell sub-assembly.    DESCRIPTION OF DRAWING(S) - The figure is a flow diagram illustrating processes for fabricating fuel cell assemblies, sub-assemblies, and unitized fuel cell assemblies.
