Abstract

A method for high-temperature electrolysis of steam and another gas to be electrolyzed, chosen from carbon dioxide and nitrogen dioxide, implemented in an electrolysis reactor includes a stack of elementary electrolysis cells each made of a cathode, an anode and an electrolyte inserted between the cathode and the anode, and a plurality of electric and fluid interconnectors each arranged between two adjacent elementary cells with one of the surfaces thereof in electric contact with the anode of one of the two elementary cells and the other one of the surfaces thereof in electric contact with the cathode of the other one of the two elementary cells. The steam is supplied and distributed to the cathode of one of the two adjacent elementary cells and either carbon dioxide or nitrogen dioxide is supplied and distributed to the cathode of the other one of the two elementary cells.
