Abstract:
1. A process for preparing a catalyst coated membrane (CCM), comprising the following steps: 1) formation of a first electrocatalytic layer on the surface of an inert support with the following steps: 2) on the first electrocatalytic layer formation of an ionomeric membrane through the following steps: 3) formation of a second electrocatalytic layer on the surface of the ionomeric membrane free from catalyst to obtain the raw CCM on the inert support through the following steps: 4) annealing of the raw CCM supported on the inert support at temperatures from 120° C. to 280° C. and obtainment of the CCM by separation of the inert support from the CCM.
