| 中文摘要: |
| 与传统的火力发电相比，燃料电池以其高效率，低污染而逐渐受到人们的广泛关注。作为平板式固体氧化物燃料电池重要部件之一的连接板的材料对电池的性能有很大的影响，综述了连接板材料，并讨论了掺杂对LaCrO3性能的影响，以及LaCrO3的制备工艺。随着运行温度的降低，金属合金可以作为连接板材料，但需解决金属合金热膨胀系数及其与其它部件匹配和高温氧化的问题。 |

| Compared with conventional fossil-fuel power generation, fuel cells are superior in the power generating efficiency and emission control and have been holding extensive interest of the industries. The interconnect is one of the important components of the planar solid-oxide fuel cell, and the materials of the interconnect have a great effect on the performance of the cell. In this presentation, properties of the materials for preparation of the interconnect were depicted. Effects of doping on the properties of LaCrO3 and the preparation processes of the material were discussed. With reduced temperatures of operation, metal alloys can be used as materials of interconnects. However, problems of the compatibility of interconnects with other components and high- temperature oxidation ought to be solved. |
