SEAL FOR SOLID POLYMER ELECTROLYTE FUEL CELL |
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 through-hole 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. |
