摘要： A fuel cell system includes a dry end unit, a wet end unit and a plurality of fuel cells. The dry end unit has a dry base plate and a dry intermediate plate. The dry intermediate plate is initially moveable relative to the dry base plate during a fabrication of the fuel cell system. The wet end unit has a wet base plate and a wet intermediate plate. The wet intermediate plate adjoins the wet base plate. The plurality of fuel cells is disposed between the dry intermediate plate and the wet intermediate plate. Each of the plurality of fuel cells includes a perimeter area that surrounds an active area. The dry intermediate plate is fixed in position relative to the dry base plate during the fabrication to maintain the active areas of the plurality of fuel cells at a target active area pressure.

摘要： A system and method for reducing the relative movement between adjacent fuel cells within a fuel cell stack includes an improved strategy for distributing an acceleration load over a fuel cell stack while maintaining stack performance after exposure to high acceleration loads. The system comprises a fuel cell stack comprising a plurality of fuel cells enclosed by a housing. A curable material occupies at least a portion of a lateral space located between the edges of each fuel cell in the stack and an interior wall of the housing. Upon occurrence of high acceleration loads within the housing, the curable material transmits the acceleration load from the housing to more evenly distribute the load to the edges of the fuel cells. A plurality of dams may be secured between the housing and the fuel cell stack forming channels for receiving the curable material.

摘要： A fuel cell system is provided which includes a compression retention enclosure with upper and lower compression shells and side sheet components coupled by interlocking hem joints. Methods for manufacturing compression retention enclosures with hem joints such that the enclosure remains sealed upon operational swelling of the fuel stack are also provided. A compression shell may be formed from a light weight composite structure having a polymeric layer interposed between steel skins, and an extension of the top steel skin may form a hemmed edge or may form a side sheet having a hemmed edge. Side sheet panels may be coupled to the end plates by interlocking two opposing hemmed edges to form the hem joint, or by sliding an opposing C-linking element between two hemmed edges held under compression force in an interlocking position.
