| 摘要 |
Oxide ceramic (A), able to conduct oxygen ions and electrons, has the perovskite structure ABO3, where the B positions are partially replaced by divalent cations with a fixed oxidation state and, the new feature, contains no cobalt. Independent claims are also included for the following: (1) membrane (M1) for use at high temperature that includes (A); (2) membrane (M2) for generating an electrical voltage comprising two layers of (A) and, between them, a layer for electrical insulation and conduction of oxygen ions; (3) method for preparing (A); (4) method for oxidizing hydrocarbons that uses M1 or M2; (5) method for separating oxygen from gases at high temperature that uses (A), M1 or M2; (6) method for generating a voltage that uses M2; (7) chemical reactor that contains (A), M1 or M2; and (8) fuel cell that contains M2. |
