Patent ID: 7722684

Claim:
A method of continuously producing a multiple layer web of fuel cell material for use with and between a pair of flow field plates or between gasket layers, comprising: 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 covering the bonding sites of the respective first and second windows.
