ABSTRACT:
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.
