ABSTRACT:
The invention relates to a method for production of a membrane/electrode unit, whereby a conducting polymer membrane is compressed with two electrodes until a given compression is achieved. Said method permits an increase in resting voltage of the membrane/electrode unit in use, the amount of damage during production is reduced and a constant thickness within a production run is achieved.
