NOVELTY - The method comprises circulating a current between an anode (32) and a cathode (33), where a density of the current is greater than 1 A/cm2, inserting water in a form of steam, which is fed under pressure to the anode, oxidizing the water in the form of steam at the anode, generating highly reactive oxygen at the anode after the oxidation, generating protonated species in a solid electrolyte (31) after the oxidation and migrating the protonated species in the electrolyte, and reducing the protonated species at a surface of the cathode in a form of reactive hydrogen atoms.    USE - The method is useful for generating hydrogen and oxygen adsorbates by steam electrolysis at 200-800 degrees C using an electrolysis cell (claimed).    ADVANTAGE - The method is capable of eliminating a risk of delamination of electrodes of the cell and industrializing the generation of hydrogen and oxygen adsorbates.    DETAILED DESCRIPTION - The method comprises circulating a current between an anode (32) and a cathode (33), where a density of the current is greater than 1 A/cm2, inserting water in a form of steam, which is fed under pressure to the anode, oxidizing the water in the form of steam at the anode, generating highly reactive oxygen at the anode after the oxidation, generating protonated species in a solid electrolyte (31) after the oxidation and migrating the protonated species in the electrolyte, and reducing the protonated species at a surface of the cathode in a form of reactive hydrogen atoms, where the solid electrolyte is made of a proton-conducting ceramic and arranged between the anode and the cathode, each of the anode and the cathode comprises a proton-conducting ceramic, and a ratio of an electroactive surface to a geometric surface of each of the anode and the cathode is equal to or higher than 100. A relative pressure partial of steam is higher or equal to 10 bars. A flow of the current is between the anode and that cathode that are made of cermet comprising a mixture of a ceramics with protonic conduction and a conducting material. The current flow is between the anode and the cathode that are made of ceramics with protonic conduction formed by a perovskite doped with lanthanide by oxidation. The method further comprises: introducing carbon monoxide (CO) and/or carbon dioxide (CO2) to the cathode of an electrolysis cell (30); reducing the introduced CO2 and/or the CO fed to the cathode from generated reactive hydrogen atoms; forming a compound of aldehyde group (CxHyOz), where x is higher than or equal to 1, y is 0-(2x+2) and z is 0-2x; introducing nitrogenized compounds to the cathode of the cell, where the nitrogenized compounds are nitrogen compounds; reducing the nitrogenized compounds introduced in the cathode from the generated reactive hydrogen atoms; forming compounds of nitrogen oxide (NOx) type, where x is higher than or equal to 1; forming compounds of hyponitrous acid monomer (NtOyHz) type following the reduction of NOx, where t is equal to or higher than 1, y is equal to or higher than 0and z is higher than or equal to zero, forming compounds of ammonia (NxHy) type following the reduction of the nitrogen compounds, where x and y are higher than or equal to 1 and 0, respectively, and reacting a highly reactive oxygen with a compound introduced to the anode so that the compound undergoes an oxygenation. The hydrogen atoms are used to carry out hydrocracking in the cathode and to convert aromatic compounds in the cathode. An INDEPENDENT CLAIM is included for an electrolysis cell.
