    摘要: A fuel cell is fitted with a current collector situated between a ribbed separator and an electrode. The current collector is comprised of a plurality of flat wires which span the peaks of the ribs of the separator. The flat wires are of sufficient thickness, width, and frequency to support the electrode against the compressive load of the fuel cell stack. The width and frequency are alterable to suppress or enhance reactant access to the electrode.

    摘要: A stretch-forming press for stamping continuously fed sheet metal includes a ram, a base member, and a feed mechanism configured to advance a strip of sheet metal through the stretch-forming press. A forming station has a die configured to form a desired pattern in the strip of sheet metal. A leveling station has a pair of opposed jaws slidably received in corresponding recesses of the stretch-forming press, with the jaws oriented at an angle with respect to a direction of travel for the strip of sheet metal as it passes through the leveling station.

    摘要: A fuel cell end plate configured to transmit substantially constant compressive forces along a surface of a fuel cell is provided. The fuel cell end plate is configured such that the compressive force is substantially constant along the surface of the fuel cell even when the surface of the fuel cell is non-parallel. The fuel cell end plate is also configured such that the surfaces of the end plate remain substantially parallel when the fuel cell end plate is in contact with a non-parallel surface of a fuel cell or fuel cell stack. The fuel cell end plate is also configured to act as a distribution manifold for the distribution of reactants and coolants to the fuel cell stack. Fuel cell assemblies including the fuel cell end plate and methods of assembling the fuel cell end plate are also disclosed.
