Assemblies for electrochemical devices

摘要

Assemblies or MEA devices (Membrane Electrode Assembly) comprising a membrane (4') and two electrocatalytic layers (5') on each side thereof, wherein:
- the area of each of the two electrocatalytic layers is lower than that of the membrane;
- on each of the two sides of the ionomeric membrane there is at least one subgasket (3'), applied on the MEA non catalyzed area;
the edges of the ionomeric membranes being enclosed among said subgaskets.
