| 20090162734 | MANUFACTURING OF FUEL CELL MEMBRANE ELECTRODE ASSEMBLIES INCORPORATING PHOTOCURABLE CATIONIC CROSSLINKABLE RESIN GASKET - A first transport system moves a web comprising a subgasketed CCM layer and an application system applies a crosslinkable resin to at least a subgasketed portion of the subgasketed CCM layer. The crosslinkable resin preferably comprises a photocurable cationic crosslinkable resin. A first curing apparatus subjects an exposed surface of the crosslinkable resin to a photo curing process to initiate curing of the crosslinkable resin. A second transport system moves a GDL into adhering contact with a partially cured exposed surface of the crosslinkable resin of the CCM layer so as to form an MEA layer. A second curing apparatus subjects the GDL, partially cured crosslinkable resin, and CCM layer structure to a thermal curing process to substantially complete curing of the crosslinkable resin. A converting system is configured to receive the MEA layer and produce a plurality of discrete MEAs from the MEA layer. | 06-25-2009 |
| 20110151350 | FUEL CELL SUBASSEMBLIES INCORPORATING SUBGASKETED THRIFTED MEMBRANES - A fuel cell roll good subassembly is described that includes a plurality of individual electrolyte membranes. One or more first subgaskets are attached to the individual electrolyte membranes. Each of the first subgaskets has at least one aperture and the first subgaskets are arranged so the center regions of the individual electrolyte membranes are exposed through the apertures of the first subgaskets. A second subgasket comprises a web having a plurality of apertures. The second subgasket web is attached to the one or more first subgaskets so the center regions of the individual electrolyte membranes are exposed through the apertures of the second subgasket web. The second subgasket web may have little or no adhesive on the subgasket surface facing the electrolyte membrane. | 06-23-2011 |

| 20100031895 | ANIMAL SHELTER WITH INTEGRATED STORAGE AND TRAINING SYSTEMS AND METHODS - In accordance with one or more embodiments of the present disclosure, a shelter for an animal comprises a base member having a plurality of recessed channels formed in an upper surface thereof and adjacent to a perimeter thereof, a plurality of wall members coupled with the recessed channels in the base member so as to form an enclosure that defines an interior space, and a roof member pivotally attached to at least one of the wall members so as to move between an open and closed configuration. The shelter comprises a removable storage member positioned between the base member and the roof member so as to vertically separate the interior space into an interior storage compartment and an interior residential compartment for the animal. The shelter comprises a movable partition member positioned between at least two of the wall members and adapted to vary the dimension of the interior residential compartment. | 02-11-2010 |
