Abstract:
1. A method for forming a fuel cell comprising: (a) applying a first curable composition at a thickness which is compressible when cured to a first fuel cell component comprising at least one fuel cell plate; (b) mating the first fuel cell component with a second fuel cell component comprising at least one fuel cell plate; (c) compressing the first fuel cell component and the second fuel cell component with a compressive force to abuttingly engage the second fuel cell component and the first curable composition with the first curable composition disposed between the first fuel cell component and the second fuel cell component; (d) curing the first curable composition to form an adhesive bond between the first and second fuel cell components; (e) applying a second curable composition at a thickness which is compressible when cured to the second fuel cell component; (f) curing the second curable composition under a compressive force; and (g) mating a third fuel cell component comprising at least one fuel cell plate to the cured second curable composition without creating an adhesive bond to the third fuel cell component.
