One-step method of bonding and sealing a fuel cell membrane electrode assembly |
摘要 |
A method is provided for making an edge-sealed fuel cell membrane electrode assembly comprising the steps of: i) providing a suitable membrane electrode assembly lay-up; ii) positioning a suitable annular layer of a thermoplastic; and iii) applying pressure and heat sufficient to melt impregnate the thermoplastic into the fluid transport layer or layers of the membrane electrode assembly lay-up and simultaneously bond the fluid transport layer or layers to the polymer electrolyte membrane of the membrane electrode assembly lay-up. The polymer electrolyte membrane of the membrane electrode assembly lay-up may be perforated in its outer sealing area. Membrane electrode assemblies made according to the method of the present invention are also provided. |
