A fuel cell system includes a plurality of stacked bipolar plate assemblies. Each of the plurality of stacked bipolar plate assemblies includes a first sub-gasket including a first peripheral edge. The first sub-gasket supports a first membrane electrode assembly (MEA). The second sub-gasket includes a second peripheral edge. The second sub-gasket supports the second MEA. The bipolar plate is disposed between the first sub-gasket and the second sub-gasket. The bipolar plate has a first side defining a first plurality of channels to receive the cathode fluid, a second side defining a second plurality of channels to receive the anode fluid, and a plurality of coolant channels defined between the first sub-gasket and the second sub-gasket. A sealing flange extends around the bipolar plate. The sealing flange seals against the first sub-gasket and the second sub-gasket. A compliant energy attenuation buffer extends around the bipolar plate and is spaced from the sealing flange.

    一种燃料电池系统,包括多个堆叠的双极板组件。多个堆叠的双极板组件中的每一个包括第一子垫片,该第一子垫片包括第一外围边缘。第一子垫片支撑第一膜电极组件MEA。第二子垫片包括第二外围边缘。第二子垫片支撑第二MEA。双极板设置在第一子垫片和第二子垫片之间。双极板具有限定接收阴极流体的第一多个通道的第一侧,限定接收阳极流体的第二多个通道的第二侧,以及限定在第一子垫片和第二子垫片之间的多个冷却剂通道。密封凸缘围绕双极板延伸。密封凸缘抵靠密封第一子垫片和第二子垫片。顺应性能量衰减缓冲器围绕双极板延伸并与密封凸缘隔开。
