ABSTRACT:
A clamping force equalizer for use in a generally rectangular fuel cell stack comprising two sheets of flexible metal sealed together at their edges and an electrically conductive material disposed between said sheets of flexible metal, said electrically conductive material being in a liquid state at a fuel cell operating material. The clamping force equalizer in accordance with this invention has a length and a width equivalent to the length and width of a horizontal plane of the fuel cell stack such that equalization of the clamping force applied to the fuel cell stack occurs over the entire horizontal plane of the fuel cell stack.
