摘要： A seal structure is disclosed for forming a substantially fluid tight seal between a UEA and a plate of a fuel cell system, the seal structure including a sealing member formed in one fuel cell plate, a seal support adapted to span feed area channels in an adjacent fuel cell plate, and a seal adapted to cooperate with a UEA disposed between the fuel cell plates, the sealing member, and the seal support to form a substantially fluid tight seal between the UEA and the one fuel cell plate. The seal structure militates against a leakage of fluids from the fuel cell system, facilitates the maintenance of a velocity of a reactant flow in the fuel cell system, and a cost thereof is minimized.

摘要： A bipolar plate for a fuel cell has a first end, a second end, a first side, and a second side. The bipolar plate also has an active region, a feed region, a perimeter region, a sealing region, and a hinge region. The sealing region is disposed between the perimeter region and each of the active region and the feed region. A plurality of outwardly extending tabs are disposed adjacent the perimeter region at each of the first end and the second end of the bipolar plate. The hinge region is disposed between the perimeter region and the outwardly extending tabs. The hinge region extends from the first side of the plate to the second side of the bipolar plate. The hinge region permits a flexing of the outwardly extending tabs to connect with peripheral electrical device without undesirably flexing the sealing region.

摘要： A system and method for processing the electric signals from a plurality of fuel cells in a fuel cell system is disclosed. Groups of the plurality of fuel cells, such as five bipolar plates, are electrically coupled to a conductive compressible connector or a circuit board, where some of the bipolar plates have a plate contactor for providing the electrical contact to either the conductive compressible connector or the circuit board. The system allows for the processing of the electric signals of every cell using fewer electrical components, thereby reducing the amount of space required and the costs associated therewith.

摘要： An embedded measurement circuit for a fuel cell stack. The fuel cell stack includes a plurality of bipolar plates that include recessed areas providing conduction and retention points for the measurement circuit. The measurement circuit has a length, a width and a thickness where the width and length of the circuit are greater than the thickness of the circuit. The measurement circuit includes a stepped cut-out portion defining steps along an edge of the length of the circuit. The measurement circuit is positioned between and among the plurality of bipolar plates so that each one of the steps of the stepped cut-out portion of the measurement circuit enables electrical contact with a separate plate and the width of the circuit is perpendicular to a plane of the plates and the thickness of the circuit is along the plane of the bipolar plates.
