    Abstract: 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.

  • Patent number: 8765322
    Abstract: A fuel cell installation includes a support structure and a cell stack assembly that is removably insertable into the support structure from an uninstalled position to an installed position during an installation procedure. The cell stack assembly includes a fitting. An interfacing structure is mounted on one of the support structure in the cell stack assembly. The interfacing structure carries a connector that is configured to receive the fitting in interconnected relationship. At least one of the fitting and the connector floats in a plane relative to the support structure during the installation procedure. In operation, the fitting engages the connector when the cell stack assembly is inserted into the support structure. The fitting is repositioned relative to the connector to ensure that the fitting and connector are aligned with one another and connected upon installation.

  • Patent number: 8728684
    Abstract: Fuel cell stacks (20) include fuel cells (22) in which internal pressure on membranes (28), caused by adjacent cross points (19) or ribs (9, 17) of gas flow field plates (7, 33) is reduced by lowering the axial load holding the stack together, after an initial high axial load, that establishes minimal possible internal resistance, has been held for between a few hours and 20 hours. The need for robust axial load restraints is also reduced. Pressure of cross points (19) can also be spread by stiffening components or adding stiffeners.
