1. A fuel-cell stack manifold retention system for use with a fuel-cell stack having a number of faces and a number of manifolds each abutting against a face of said fuel-cell stack, said fuel-cell manifold retention system holding each of said manifolds against the corresponding face of said fuel-cell stack and comprising:a number of strap members, each said strap member extending over an extent of a corresponding manifold of the fuel-cell stack and expanding, contracting and sliding, and each said strap member being spring loaded to provide said expansion and contraction, and an attachment assembly for attaching said strap members to said fuel-cell stack; whereby the strap members hold the manifolds to the fuel-cell stack in a manner to accommodate for changes in the fuel-cell stack geometry.
