    摘要： A sealed membrane electrode assembly (MEA) and a method of sealing the MEA comprises the steps of providing a frame around a periphery of the MEA to form a framed MEA; providing a through-hole in the frame; placing the framed MEA into a seal mold, the seal mold comprising a reservoir region, a seal bead region, and at least one runner region; feeding a flow-processable seal material into the reservoir region in the seal mold that is aligned with the throughhole in the frame; feeding the flow-processable seal material from the reservoir region to the seal bead region through the at least one runner region; wherein a hydraulic diameter of the at least one runner region is less than a hydraulic diameter of the reservoir region.

    摘要： An exemplary fuel cell component comprises a reactant distribution plate including a plurality of channels configured for facilitating gas reactant flow such that the gas reactant may be used in an electrochemical reaction for generating electricity in a fuel cell. Each of the channels has a length that corresponds to a direction of reactant gas flow along the channel. A width of each channel is generally perpendicular to the length. A depth of each channel is generally perpendicular to the width and the length. At least one of the width or the depth has at least two different dimensions at a single lengthwise location of the channel.
