    摘要： CCM formed of a membrane having on one of the two surfaces a first electrocatalytic layer containing a catalyst and on the other one a second electrocatalytic layer containing a catalyst, said electrocatalytic layers and said membrane containing (per)fluorinated ionomers, said CCM having the following characteristics:
    - size variations, for both the orthogonal directions of the plane xy, lower than 15%, by dipping the CCM, after drying at 105°C under vacuum for one hour in demineralized water at 100°C for 30 minutes;
    - the CCM remains substantially unchanged after having been subjected to treatments of 60 cycles by dipping in water at 80°C for 8 hours and then in water at the temperature of 25°C for 16 hours;
    - the orthogonal projection of the perimeter of the first electrocatalytic layer on the second layer is distant from the perimeter of the second layer at least 1 mm in each point.

    equivalent weight between 700 and 1600 g/eq;
    side chains of formula: -O-CF 2 -CF 2 -SO 3 - M + , wherein M is hydrogen or an alkaline metal;

    said membrane having the following combination of properties:

    size variations, for both the orthogonal directions xy of the plane, lower than 15%, measured after dipping of the ionomeric membrane, dried at 105°C under vacuum for one hour, in demineralized water at 100°C for 30 minutes;
    the membrane, dipped at the temperature of 50°C for 22 hours in a water/ethanol mixture containing 40% by weight of alcohol, remains integral.
