Abstract
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.
