Abstract
Between the high electronic conduction structures of the multilayer assembly an electric voltage signal is applied of which at least one portion includes an alternating component which has an amplitude between 0.05 and 100 volts and a frequency lower than 5 kHz and preferably between 2 and 2000 Hz so as to generate within the multilayer assembly an alternating ion current susceptible of producing a heating of the ion conducting macromolecular material by Joule effect. Application to the heating of electrochemical current generators in thin layers with solid polymer electrolyte or to the surface heating of elements of various regular or irregular shapes of which the surface is coated with the multilayer assembly.
