    摘要: An exemplary flow field includes a plurality of flow channel portions. There are n inlet portions configured for introducing a fluid into the flow field. A plurality of first pass portions direct fluid flow in a first direction. A plurality of second pass portions direct fluid flow in a second direction that is generally parallel to and opposite to the first direction. A plurality of third pass portions direct fluid flow in the first direction. n outlet portions are configured to allow fluid to exit the flow field. n is an integer and a number of the portions in at least one plurality of pass portions is a non-integer multiple of n.

    摘要: An example seal assembly includes a first seal that is configured to be placed between a fuel cell manifold and a fuel cell stack. The first seal establishes a recessed area within a side of the first seal that faces the fuel cell stack. The fuel cell seal assembly further includes a second seal that is configured to be placed between the first seal and the fuel cell stack within the recessed area. An example method of sealing a fuel cell interface includes holding a first seal within a groove established within a manifold and holding a second seal within a recessed area established within the second seal. The method limits flow of a fuel cell fluid using a first seal and the second seal.

    摘要: Ejectors (22, 59) are configured to receive fresh fuel gas at the motive inlet (27, 60) and to receive fuel recycle gas at the suction inlet (29, 64, 65). Each ejector is disposed either a) within a fuel inlet/outlet manifold (13, 109) or adjacent to and integral with the fuel inlet/outlet manifold. The ejector draws fuel recycle gas directly from the fuel outlet manifold and, after mixing with fresh fuel, is expanded (34, 76) to lower the pressure and is then fed directly into the fuel inlet manifold (14, 80, 109). The ejector may be within an external manifold (13, 92) or an internal manifold (109). The ejector (59) may be formed of perforations clear through a plate (80), which is closed on either side by other plates (83, 85), or the ejector may be formed by suitable sculpture of fuel cells (12) having internal fuel inlet (109) and fuel outlet (15) manifolds.
