  • Sealing membrane electrode assemblies for electrochemical fuel cells
    Patent number: 6716550
    Abstract: An elastomer may be used to construct a separate, moldable part that engages the edge a membrane electrode assembly (MEA) to thereby seal the MEA. The seal has a groove defining two sealing portions separated by a web portion. The groove of the seal then engages the edge of the MEA and can maintain a tight fit without the need for additional adhesives. Additional features may extend laterally from the web portion to assist in separating cathode and anode plates and/or encompass, for example, manifold openings.
