Tóm tắt

 Method of making a membrane electrode assembly comprising: providing a membrane comprising a perfluorinated sulfonic acid
  providing a first transfer substrate
  applying to a surface of the first transfer substrate a first ink, said first ink comprising an ionomer and a catalyst
  applying to the first ink a suitable non-aqueous swelling agent
  forming an assembly comprising: the membrane
  and the first transfer substrate, wherein the surface of the first transfer substrate comprising the first ink and the non-aqueous swelling agent is disposed upon one surface of the membrane
  and heating the assembly at a temperature of 150.degree. C. or less and at a pressure of from about 250 kPa to about 3000 kPa or less for a time suitable to allow substantially complete transfer of the first ink and the second ink to the membrane
  and cooling the assembly to room temperature and removing the first transfer substrate and the second transfer substrate.
