| 发明名称 | Functional layer for high-temperature fuel cells and method for production | ||
| 摘要 | Described is a functional layer for high-temperature fuel cells and to a method for the production of functional layers. The functional layer is in particular a low-sintering, electrically conductive, ceramic layer which is formed between an interconnector and a cathode of a fuel cell. The functional layer is formed from a material which has at least two phases. A first phase is a perovskite ceramic material containing bismuth-cobalt and a second phase is a bismuth manganite and/or bismuth cobaltite (Bi—Mn—Co—0). | ||

| 主权项 | 1. A functional layer for a high-temperature fuel cell, comprising: a material comprising at least two phases, a first phase of the at least two phases being a perovskite ceramic material containing bismuth-cobalt, a second phase of the at least two phases being at least one of a bismuth manganite and bismuth cobaltite, wherein the layer is arranged between an interconnector and a cathode, wherein the first phase is formed with a perovskite containing bismuth-cobalt in accordance with the formula Ln1−x−zBizAxM1−yCOyO3−δ, where x≦0.35, 0≦z≦0.05, 0.1≦y≦0.6, Ln=rare earths, A=alkaline earth, M=transition metals. | ||
