| 摘要 |
The present invention relates to high- temperature solid oxide fuel cells, in particular to rotationally symmetrical high- temperature solid oxide fuel cells. The inventive oxide-ceramic high- temperature fuel cell having one or more gas channel (s) open at at least one end. The fuel cell has a substrate surrounding the gas channel (s) at least sectionally, preferably completely. The gas channel (s) and/or the substrate surrounding the gas channel (s) has/have (a) changing cross-sections (s), preferably (a) conically tapering cross -section (s), seen in the direction of the longitudinal axis/axes of the gas channel (s). oxide-ceramic high-temperature fuel cell |
