| 摘要 |
The invention provides a solid oxide fuel cell device and a fuel cell system incorporating a plurality of the fuel devices, each device including an elongate substrate having a first cold end region adjacent a first end, a second cold end region adjacent a second end, and a hot reaction zone between the first and second cold end regions, wherein the hot reaction zone is configured to be heated to an operating reaction temperature, and the first and second cold end regions are configured to remain at a low temperature below the operating reaction temperature. A fuel inlet is positioned in the first cold end region with a respective fuel outlet positioned in either the hot reaction zone or the second cold end region, and an elongate fuel passage is coupled therebetween at least partially extending through the hot reaction zone. Similarly, an oxidizer inlet is positioned in the second cold end region with a respective oxidizer outlet positioned in either the hot reaction zone or the first cold end region, and an elongate oxidizer passage is coupled therebetween at least partially extending through the hot reaction zone in parallel and opposing relation to the elongate fuel passage. An anode is positioned adjacent the fuel passage in the hot reaction zone and is electrically coupled to a first exterior contact surface on the elongate substrate in at least one of the first and second cold end regions. A cathode is positioned adjacent the oxidizer passage in the hot reaction zone and is electrically coupled to a second exterior contact surface on the elongate substrate in at least one of the first and second cold end regions. Electrical connections are made to the exterior contact surfaces.
