Abstract
Un dispositivo electroquímico para separar oxígeno de un gas que contiene oxígeno comprende una pluralidad de placas electrolíticos solidas planares conductivas a los iones e interconexiones eléctricamente conductivas impermeables al gas ensambladas en un componente apilado de multiples celdas. El material del ánodo y cátodo eléctricamente conductivo se aplica en los lados opuestos de cada placa electrolítica. Un sello de ánodo hermético al gas se une entre el lado del ánodo de cada placa electrolítica y el lado de ánodo de la interconexion adyacente. Un electrodo de polarizacion aplicado al lado de ánodo de cada placa electrolítica entre el sello de ánodo y el borde del ánodo, elimina la falla del sello de ánodo al minimizar el potencial eléctrico a través del sello. El potencial de sello se mantiene abajo de 40 mV y de preferencia abajo de aproximadamente 25 mV. El sello hermético al gas se aplica entre los lados de cátodo de cada placa electrolítica y la interconexion adyacente de modo que los sellos de ánodo y cátodo se desplazan raídamente en los lados opuestos de la placa. La combinacion de los electrodos de polarizacion y los sellos de desplazamiento es particularmente efectiva para eliminar la falla del sello de ánodo.
