    摘要: A flow field plate for a fuel cell includes features in the gas input area that enhance gas distribution to the flow field channels. The input area of the flow field plate directs gases from an input manifold to the flow field channels. The input area includes one or more input channels which are defined by input channel walls. One or more features are included within the input area to enhance the distribution of the gas to the flow field channels. The gas distribution enhancement features may provide support for a sealing element to reduce blockage of the channels and/or may provide a path for fluid communication between adjacent input channels.

    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.
