A process for preparing a solid composite electrolyte comprising at least one compound of the BIMEVOX family is provided. The process comprises at least one step of preparing a mixture of one or more compounds of the BIMEVOX family with one or more chemically inert compounds, at least one step of compacting the mixture obtained, and at least one sintering step during which the temperature reached, over a nonzero time interval, has a value greater than the optimum sintering temperature for the compound of the BIMEVOX family.

Process for preparing a composite electrolyte based on BIMEVOX and the use of said compound in separating oxygen from a gas mixture

Process for separating oxygen from a gas mixture containing it employs a solid-electrolyte electrochemical cell, where the cell includes a homogeneous structure of one or more BIMEVOX derivatives, with dynamic electrodes created 'in situ' that are reversible and self-adaptive, and at least two current collectors.

A regenerative oxygen trap which uses an oxygen absorbing material formed of a solid solution of metal oxides having both an ionic conductivity through 0.sup.2.sup.- ions and a nonzero electrical conductivity, the material forming part of a circuit which also includes a source of electricity. The material is converted in an inert gas to its reduced form by the passage of a current therethrough, in which form it is effective for the absorption of gaseous oxygen.
