METHOD FOR GENERATING HYDROGEN AND OXYGEN BY STEAM ELECTROLYSIS

THE PRESENT INVENTION RELATES TO A METHOD FOR GENERATING HYDROGEN AND OXYGEN ADSORBATES BY STEAM ELECTROLYSIS AT 200 TO 800°C USING AN ELECTROLYSIS CELL (30) COMPRISING A SOLID ELECTROLYTE (31) WHICH IS MADE OF A PROTON CONDUCTING CERAMIC AND WHICH IS ARRANGED BETWEEN AN ANODE (32) AND A CATHODE (33...

Zusammenfassung:	THE PRESENT INVENTION RELATES TO A METHOD FOR GENERATING HYDROGEN AND OXYGEN ADSORBATES BY STEAM ELECTROLYSIS AT 200 TO 800°C USING AN ELECTROLYSIS CELL (30) COMPRISING A SOLID ELECTROLYTE (31) WHICH IS MADE OF A PROTON CONDUCTING CERAMIC AND WHICH IS ARRANGED BETWEEN AN ANODE (32) AND A CATHODE (33) EACH OF WHICH COMPRISES A PROTON CONDUCTING CERAMIC AND THE RATIO OF THE ELECTROACTIVE SURFACE TO THE GEOMETRIC SURFACE OF EACH OF WHICH IS EQUAL TO AT LEAST 10 SAID METHOD COMPRISING THE FOLLOWING STEPS: CIRCULATING A CURRENT BETWEEN THE ANODE (32) AND THE CATHODE (33) WHEREIN THE DENSITY OF THE CURRENT IS NO LESS THAN 500 MA/CM; INSERTING WATER IN THE FORM OF STEAM WHICH IS FED UNDER PRESSURE TO THE ANODE (32); OXIDIZING SAID WATER IN THE FORM OF STEAM AT THE ANODE (32) AND GENERATING HIGHLY REACTIVE OXYGEN AT THE ANODE (32) AFTER SAID OXIDATION; GENERATING PROTONATED SPECIES IN THE ELECTROLYTE (31) AFTER SAID OXIDATION AND MIGRATING SAID PROTONATED SPECIES IN THE ELECTROLYTE (31); AND REDUCING SAID PROTONATED SPECIES AT THE SURFACE OF THE CATHODE (33) IN THE FORM OF REACTIVE HYDROGEN ATOMS.
