    摘要: A stackable unitized fuel cell system includes a cooling capability. A unitized fuel cell system includes a unitized fuel cell assembly having a first flow field plate, a second flow field plate, and a membrane electrode assembly (MEA) provided between the first and second flow field plates. In one configuration, a cooling structure is separable with respect to the unitized fuel cell assembly. In another configuration, the cooling structure is integral to the unitized fuel cell assembly. A retention arrangement is provided on one or both of the unitized fuel cell assembly and cooling structure. The retention arrangement is configured to facilitate mating engagement between the unitized fuel cell assembly, the cooling structure, and adjacent unitized fuel cell systems of a fuel cell stack.

    摘要: A unitized fuel cell assembly includes a first flow field plate, a second flow field plate, and a membrane electrode assembly (MEA) provided between the first and second flow field plates. A hard stop arrangement, in one configuration, is provided between the first and second flow field plates. The hard stop arrangement is dimensioned to limit compressive forces imparted to the MEA upon establishment of contact between the first and second flow field plates under pressure. A sealing arrangement is provided between the first and second flow field plates and peripheral to the MEA. The unitized fuel cell assembly is configured as a stand-alone fuel cell unit that can be used alone or in a stack of fuel cell units.

    摘要: A registration arrangement for a fuel cell stack assembly incorporates registration posts and registration apertures or recesses. Fuel cell assemblies of the stack may include first and second flow field plates and a membrane electrode assembly (MEA) having an active area. Registration apertures are defined in each of the MEA and the first and second flow field plates. The respective registration apertures are situated within non-active areas of the MEA when the first and second flow field plates and the MEA are in axial alignment. Registration posts are configured for reception within the registration apertures. Each of the registration posts has an outer surface differing in shape from a shape of the inner surface of the registration apertures. The inner surface of the registration apertures contact the outer surface of the registration posts at a plurality of discrete press-fit locations.
