Abstract

A method is provided for producing a membrane electrode unit, provided with a peripheral seal and a peripheral sealing frame for an electrochemical cell, comprising the steps of: (A) producing a sandwich-like arrangement, forming the membrane electrode unit, from a membrane and two gas diffusion electrodes, (B) connecting the sandwich-like arrangement to a seal that extends around said electrodes at the lateral outer edge thereof, said seal at the same time establishing the connection to the sealing frame that extends laterally around the membrane electrode unit.
