초록

A method for forming a fuel cell assembly including the pre-final-assembly step of forming a plurality of fuel cell sub-assembly modules, each module including a predetermined number of individual fuel cell repeating units, for example, ten. Each module may be leak and performance tested and certified prior to inclusion in the final fuel cell stack, thus limiting potential rework to only an individual module and only before assembly of the final stack. Preferably, each module is assembled on an assembly fixture having alignment rods, using a combination ...

청구항

What is claimed is: 1. A method for forming a fuel cell assembly, comprising the steps of: a) forming a fuel cell sub-assembly module containing at least two bonded together fuel cell units, said at least two fuel cell units each including an anode, a cathode, and a membrane electrode assembly, wherein said at least two fuel cell units are bonded together using at least one elastomeric gasket and at least one gasketing element, and wherein one of said at least one elastomeric gasket or said at least one gasketing element is cured prior to bonding togeth...
