Interfacial and edge seals for unitized electrode assemblies of fuel cell stack assembly

摘要

A unitized electrode assembly for a fuel cell stack assembly, includes a membrane electrode assembly having a first side, a second side, a peripheral edge area and a plurality of perforations along the peripheral edge area; a cathode substrate adjacent to the first side; an anode substrate adjacent to the second side; and a seal material bonding the cathode substrate to the anode substrate and extending through the plurality of perforations.
