A proton exchange membrane ("PEM") fuel cell stack and components of the fuel cell stack are provided. The fuel cell employs a plurality unique manifold assembly devices that allows for even distribution of the fuel source, e.g., hydrogen, to the anode side of the PEM and is designed so that the entrance orifice for the fuel source is larger than the exit orifice for the fuel source and/or reaction products. A pressure sensitive seal or a flexible, contoured seal is positioned around perimeter borders of the anode face of the PEM and the bipolar separation plate ("BSP") to form a seal between the BSP and PEM. A sleeve, which is open-D-shaped in cross-section is provided that allows for even distribution of pressure on assembly of multiple fuel cells to form a fuel cell stack of the invention.
