Abstract
A load frame with mechanical springs for providing compression to a fuel cell stack during assembly and operation of a fuel cell assembly. The stack assembly load frame includes a base plate for supporting the stack, a moveable spring holder above the stack, a retaining plate above the spring holder, and tubular supports or rods retaining the post-sintered spacing established by the applied load defining the spacing of the base plate from the retaining plate. A spring for maintaining compression in each stack is positioned between the spring holder and the retaining plate. The invention further comprises a method for assembling a fuel cell assembly to provide an adequate compressive load to the stack during assembly and operation.
