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.
