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.
