NOVELTY - The energy conversion system comprises a first electrode (6), a second electrode (7), and an inter-electrode comprising a functional medium between the first and second electrodes. The first electrode is produced from an electrical conductive unit to be placed at the same electrical potential so as to constitute the first electrode. The medium comprises an aqueous electrolyte composed of water, an alkaline base, and alkaline silicate having a concentration of 5-30 wt.% of the aqueous electrolyte. The electrical conductive unit is elongated, and has a total length L of greater than 1x 103 m.    USE - The system for conversion of energy is useful in devices including an electrolysis device, a photolysis device, an electrosynthesis device, an electric generator by inverse electrolysis, a fuel cell, an electrical battery, an ozone generator, an electrodialysis capacitor, a discharge lamp, a photovoltaic generation and a solar cell with photo-active driver (claimed).    ADVANTAGE - The energy conversion system provides high performance and long life to the electrochemical cell, increases the conductivity of the electrolyte while ensuring adequate protection of the conductive elements of the electrochemical cell without any degradation, and can be economically and energy efficiently manufactured with high corrosion resistance.    DETAILED DESCRIPTION - The energy conversion system comprises a first electrode (6), a second electrode (7), and an inter-electrode comprising a functional medium between the first and second electrodes. The first electrode is produced from an electrical conductive unit to be placed at the same electrical potential so as to constitute the first electrode. The medium comprises an aqueous electrolyte composed of water, an alkaline base, and alkaline silicate having a concentration of 5-30 wt.% of the aqueous electrolyte. The electrical conductive unit is elongated, has a total length L of greater than 1x 103 m, a curved section and curved radius R, which is lower than 50x 10-6 m. The inter-electrode has a thickness of 1x 10-9 m to 2x 10-2 m. The ratio (L/R) of the total length of the electrical conductive unit and its curved radius is greater than or equal to 2.5x 107 so that the first electrode provides an increase in electric field effect from millimeter to nanometer scale. The first electrode is made of a first material and the second electrode is made of a second material different from the first material. The first electrode acts as an anode and the second electrode acts a cathode. The anode comprises electronegative elements constituting the cathode to generate an elevation of the current flowing through the anode and the cathode.
