Abstract

Una membrana de transporte de ion de electrolito solida que comprende un material de matriz que conduce por lo menos un tipo de ion, tal como ion de oxígeno y, por lo menos un componente que es físicamente distinguible del material de matriz y que mejora por lo menos las propiedades mecánicas, las propiedades catalíticas y/o el comportamiento de concretacion del material de matriz. El componente está presente de una manera que evita la conductividad electronica continua a través del componente de un lado a otro de la membrana. Un recubrimiento poroso está colocado preferiblemente sobre la membrana para mejorar la velocidad de las reacciones de superficie que involucran la especie gaseosa.
