A fuel cell stack manifold system in which a flexible manifold body includes a pan having a central area, sidewall extending outward from the periphery of the central area, and at least one compound fold comprising a central area fold connecting adjacent portions of the central area and extending between opposite sides of the central area, and a sidewall fold connecting adjacent portions of the sidewall. The manifold system further includes a rail assembly for attachment to the manifold body and adapted to receive pins by which dielectric insulators are joined to the manifold assembly.

Flexible fuel cell gas manifold system

A manifold and manifold sealing assembly for use with a fuel cell stack having a plurality of faces in which the assembly includes a plurality of frame assemblies and a plurality of manifolds, and at least one frame assembly adjacent a given face of the fuel cell stack provides support for a part of the frame assembly abutting the face of the stack adjacent the one face. Additionally, the manifold abutting the one frame assembly and the manifold abutting the supported frame assembly are adapted to sealingly engage in the area of support.

Manifold and sealing assembly for fuel cell stack

A fuel cell stack compression system in which a spring assembly and mechanical linkage assembly are used in conjunction with tie rods and tie bars to apply a compressive load to a fuel cell stack. The linkage assembly includes a lever and three pins to redirect the force or movement generated by the spring assembly into a movement or force for the tie rods. The tie rods, in turn, connect to the tie bars which span the top end plate of the fuel cell stack and transfer the load to the stack. The linkage also includes a slotted bearing which compensates for the circular arc formed by the lever and allows the spring assembly to be rigidly mounted under the bottom end plate. The spring assembly comprises multiple springs arranged in parallel and designed to provide a non-linearly decreasing load as the stack compresses due to cell consolidation. This load profile reduces overall stack shrinkage while providing high pressure at the beginning of life to insure proper cell-to-cell contact.
