Abstract:
PCT No. PCT/FR93/00872 Sec. 371 Date May 16, 1994 Sec. 102(e) Date May 16, 1994 PCT Filed Sep. 13, 1992 PCT Pub. No. WO94/06545 PCT Pub. Date Mar. 31, 1994The present invention relates to an electrochemical cell comprising a solid electrolyte conductive for O2- anions in contact with an anode and a cathode of identical or different composition, the electrolyte solid being comprised of a composition derived from Bi4V2O11 of which at least one of the cationic constituent elements is substituted by at least one substituting element chosen such that the gamma phase structural type of Bi4V2O11 is maintained, as well as the equilibrium of charges, at least one of the anode or the cathode including two parts, a first part being of a mixed electronic and ionic conductive material in contact with the solid electrolyte, the second part being an electronic conductive material superposed on the first part. The invention equally relates to the use of the electrochemical cell with a view towards the separation or the extraction of oxygen.
