| 摘要 |
The present invention relates to a double-layer electrolyte system for medium-low temperature fuel cells, comprising: a first electrolyte layer, a mixture of proton conductive solid oxide and perovskite oxide; and a second electrolyte layer, a proton conductive solid oxide. The first electrolyte layer is located at a cathode which is a positive electrode, and the second electrolyte layer is located at an anode which is a negative electrode. Furthermore, the present invention relates to medium-low temperature fuel cells. In each of the medium-low temperature fuel cells, the cathode as the positive electrode, the first electrolyte layer, the second electrolyte layer, and the anode as the negative electrode are staked sequentially. The first electrolyte layer is a mixture of the proton conductive solid oxide and the perovskite oxide and the second electrolyte layer is the proton conductive solid oxide. The first electrolyte layer, a mixture of BZY and LSM (La1-xSrxMnO3), is located at the positive electrode (cathode) and the second electrolyte layer, BZY, is located at the negative electrode (anode). Additionally, the present invention relates to multilayer medium-low temperature fuel cells on which two or more medium-low temperature fuel cells are staked. |
