A pair of reactant cover plates, e.g., fluid manifolds or protective covers (), on opposite sides of a fuel cell stack () are drawn to the fuel cells () and pressure plates () by tensioning lines, e.g., cables () or straps (), which may extend around structures, e.g., pins or extensions () extending outwardly from the ends of the cover plates or guides () on the stack, e.g., on the pressure plates in a closed loop, and are tensioned by a tensioning device, such as a turnbuckle ().

Fuel cell cover plate tie-down

A pair of reactant gas manifolds (and) on opposite sides of a fuel cell stack () are sealed to the fuel cells () and pressure plates () by means of pressure applied by load cables (). The centers of the manifolds are prevented from having leakage between them and the end plates by means of a tensioning system comprising a plurality of pins () extending outwardly from the ends of the manifolds, and tensioning cables () extending around the pins in a closed loop and tensioned by a turnbuckle ().
