(JP2000086204-A)   NOVELTY - Oxygen is separated from an oxygen-containing gas in an electrolytic cell stack in which anode and cathode seals are radially offset such that the seals do not overlap on opposite sides of the electrolyte plate.    USE - For the separation of oxygen from oxygen-containing gases, e.g. for the production of high-purity oxygen from air and in the removal of residual oxygen from inert gases such as argon or nitrogen, e.g. in fuel cells and gas analysis and monitoring.    ADVANTAGE - Anode seal failure is eliminated, as the anode and cathode seals are radially offset, such that the seals do not overlap on opposite sides of the electrolyte plate. The electrolyte potential in the seal region is modified or regulated such that current flow through the anode seal is minimized.
