    Abstract: A fuel cell component includes a first fluid distribution layer, a second fluid distribution layer, a cap layer, a third fluid distribution layer, and a pair of fluid diffusion medium layers. The individual layers are polymeric, mechanically integrated, and formed from a radiation-sensitive material. The first fluid distribution layer, the second fluid distribution layer, the cap layer, the third fluid distribution layer, and the pair of fluid diffusion medium layers are coated with an electrically conductive material. A pair of the fuel cell components may be arranged in a stack with a membrane electrode assembly therebetween to form a fuel cell.

    Abstract: A fuel cell stack of at least two fuel cells, each fuel cell having a unitized electrode assembly (UEA) including a membrane electrode assembly (MEA), a sub-gasket and gas diffusion media (DM), and positioned between modified stamped field-flow plates. The sub-gasket frames the MEA resulting in an overlap area between the MEA and the inner perimeter of the sub-gasket. The UEA is disposed between a pair of stamped flow-field plates which align in adjacent fuel cells to form a bipolar plate. The bipolar plate has an active region, an overlap region and a seal region. The active region is configured with channel and land features which provide reactant flow channels and coolant passages for the fuel cell. The configuration of features in the overlap region, however, is modified from the configuration in the active region so that the overlap region may sustain sufficient mechanical sealing pressure, and to prevent coolant and reactant bypass without impeding coolant and reactant flow in the active area. Modified channel and land feature configurations for the overlap region are exemplified.
