    摘要： A fuel cell system is provided including a fuel cell stack having a first end and second end; an upper end unit adjacent the first end of the fuel cell stack; a lower end unit adjacent the second end of the fuel cell stack; and a compression retention system disposed external to the fuel cell stack. The compression retention system includes at least one restraining member extending from the upper end unit to the lower end unit, fastening means disposed at opposite ends of the at least one restraining member, and compressive means interposed between at least one of the fastening means and the end units; wherein the fastening means and the compressive means urge the upper end unit toward the lower end unit, thereby applying compressive force to the fuel cell stack. Also provided is a method for assembling the fuel cell system.

    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.
