摘要： A fuel cell sub-assembly includes first and second flow field plates each comprising several fastener apertures defined at a number of fastening locations. A membrane electrode assembly is situated between the first and second flow field plates and includes several fastener apertures defined at a number of fastening locations, the respective fastener apertures aligned to define fastening holes. A form-in-place fastener formed of an elastomeric material is disposed in each of the fastening holes. The elastomeric material facilitates volumetric displacement of the form-in-place fasteners in response to placing the fuel cell sub-assembly in compression.

摘要： Fabrication methods for making a gas diffusion layer incorporating a gasket (GIG) fuel cell subassemblies via roll-to-roll processes are described. A material processable by one or both of heat and pressure having spaced apart apertures is transported to a bonding station. A first gasket layer having gas diffusion layers arranged in relation to spaced apart apertures of a first gasket layer is transported to the bonding station. The heat/pressure processable material is aligned with the first gasket layer and the gas diffusion layers. At the bonding station, the heat/pressure processable material is bonded to the first gasket layer and the gas diffusion layers. After bonding, the heat/pressure processable material forms a second gasket layer that attaches the gas diffusion layers to the first gasket layer.

摘要： A Pt—Ni catalyst is provided which demonstrates an unusually high oxygen reduction mass activity. In some embodiments, the Pt—Ni catalyst is a Pt—Ni binary alloy. In some embodiments, the catalyst may be characterized as having a Pt fcc lattice parameter of less than 3.71 Angstroms or 0.371 nm. In some embodiments the catalyst has a Pt fcc lattice parameter of between 3.69 Angstroms (or 0.369 nm) and 3.73 Angstroms (or 0.373 nm). In some embodiments, the catalyst may be characterized as having a composition of close to PtxNi(1-x), where x is between 0.2 and 0.4. In some embodiments the catalyst comprises nanostructured elements comprising microstructured support whiskers bearing a thin film of nanoscopic catalyst particles comprising a catalyst material described above. The catalyst may be particularly useful as a fuel cell catalyst and more specifically as a fuel cell cathode catalyst.

摘要： A gas diffusion layer incorporating a gasket (GIG) is described along with assemblies incorporating the GIG subassembly. Processes for making the GIG and membrane electrode assemblies (MEAs) incorporating the GIG are also described. A GIG subassembly includes a gas diffusion layer (GDL) and a gasket bonded to the GDL. The gasket includes a first gasket layer and a second gasket layer. The second gasket layer is formed of a gasket material in contact with the first gasket layer and the GDL. The gasket material of the second gasket layer bonds the GDL to the first gasket layer. An adhesive layer, and optionally a removable adhesive liner, is disposed on a surface of the first gasket layer opposite the second gasket layer. In some MEA configurations, the GDL is disposed within an aperture in the first gasket layer.
