Abstract
The present invention relates to a new method for the production of electrochemical cells, in particular individual cells for fuel cells and stacks, in which the individual components of a membrane electrode assembly are compressed and bonded by use of ultrasonic waves and the absence of any further additional heating. The method according to the invention allows faster cycles during the lamination of the membrane electrode assemblies.
