A method of manufacturing an electrochemical cell comprising providing a multi-layered ceramic-metal capacitor comprising layered structure of a ceramic dielectric material, a first internal electrode comprising interdigitated plates, and a second internal electrode comprising interdigitated plates, being enclosed in a dielectric coating, and opening an area in the dielectric coating at one side of the multi-layered ceramic-metal capacitor to expose edges of the side of the layered structure of the ceramic dielectric material, the first internal electrode and the second internal electrode for producing a working area of an electrochemical cell characterised in that after an opening is formed in the coating on side of the multi-layered ceramic-metal capacitor, exposing layers of ceramic dielectric material, side edges (2") of metal plates of the first internal electrode, and side edges (3") of the metal plates of the second internal electrode, signal transmitting means (8', 8") for transmitting signals from the working area via electrodes (2, 3) are connected to terminals (6, 7) of the electrodes (2, 3). afterwards, the opening is covered by an easily removable layer of protecting material to protect the working area from covering with permanent insulating material, subsequently the terminals (6, 7) of the electrodes (2, 3) are covered with permanent insulting material to protect the terminals (6, 7) from solutions during further modifications of edges (2", 3") of the first and the second electrodes (2, 3), afterwards the easily removable layer of insulating material from the opening is removed once again exposing edges (2", 3") of the first and the second electrodes (2, 3) for further treatment, afterwards the multi-layered capacitor is fully immersed into a solution for electrochemical deposition of metal and/or other modifying materials on the exposed edges (2") of the first electrode, where an electric potential is applied to the terminal of the first internal electrode, the first terminal being connected to potentiostat/galvanostat while the terminal of the second internal electrode is disconnected, afterwards solution for electrochemical deposition of metal and/or other modifying materials is changed for electrochemical deposition of a different material of metal and/or other modifying materials onto the exposed edges (3") of the second electrode, where an electric potential is applied to the terminal of the second electrode, the second terminal being connected to potentiostat/galvanostat while the terminal of the first electrode is disconnected, where after the electrochemical deposition the side edges (2") of metal plates of the first internal electrode, and side edges (3") of the metal plates of the second internal electrode exposed in the opening of the coating on side of the multi-layered ceramic-metal capacitor are submerged into a medium of liquid electrolyte. after an opening is formed in the coating on side of the multi-layered ceramic-metal capacitor, exposing layers of ceramic dielectric material, side edges (2") of metal plates of the first internal electrode, and side edges (3") of
