Abstract:
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 together said at least two fuel cell units, and the other of said at least one elastomeric gasket and said at least one gasketing element is cured during the bonding together of said at least two fuel cell units; b) testing said sub-assembly module; and c) joining together a plurality of sub-assembly modules to form said fuel cell assembly.
