| Zusammenfassung: | A gasketed fuel cell membrane electrode assembly is provided comprising a fuel cell membrane electrode assembly and a gasket, where the gasket comprises a closed-cell foam rubber, typically a silicone foam rubber. The membrane electrode assembly (MEA) typically comprises a peripheral sealing zone, in which the MEA consists essentially of its central ion conducting membrane layer or catalyst coated membrane layer and a closed-cell foam rubber gasket optionally attached with an adhesive. Typically the gasketed fuel cell membrane electrode assembly according to the present invention comprises no hard stop layer. |
